Date
open class Date : Cloneable, Comparable<Date!>, Serializable
kotlin.Any | |
↳ | java.util.Date |
The class Date
represents a specific instant in time, with millisecond precision.
Prior to JDK 1.1, the class Date
had two additional functions. It allowed the interpretation of dates as year, month, day, hour, minute, and second values. It also allowed the formatting and parsing of date strings. Unfortunately, the API for these functions was not amenable to internationalization. As of JDK 1.1, the Calendar
class should be used to convert between dates and time fields and the DateFormat
class should be used to format and parse date strings. The corresponding methods in Date
are deprecated.
Although the Date
class is intended to reflect coordinated universal time (UTC), it may not do so exactly, depending on the host environment of the Java Virtual Machine. Nearly all modern operating systems assume that 1 day = 24 × 60 × 60 = 86400 seconds in all cases. In UTC, however, about once every year or two there is an extra second, called a "leap second." The leap second is always added as the last second of the day, and always on December 31 or June 30. For example, the last minute of the year 1995 was 61 seconds long, thanks to an added leap second. Most computer clocks are not accurate enough to be able to reflect the leap-second distinction.
Some computer standards are defined in terms of Greenwich mean time (GMT), which is equivalent to universal time (UT). GMT is the "civil" name for the standard; UT is the "scientific" name for the same standard. The distinction between UTC and UT is that UTC is based on an atomic clock and UT is based on astronomical observations, which for all practical purposes is an invisibly fine hair to split. Because the earth's rotation is not uniform (it slows down and speeds up in complicated ways), UT does not always flow uniformly. Leap seconds are introduced as needed into UTC so as to keep UTC within 0.9 seconds of UT1, which is a version of UT with certain corrections applied. There are other time and date systems as well; for example, the time scale used by the satellite-based global positioning system (GPS) is synchronized to UTC but is not adjusted for leap seconds. An interesting source of further information is the United States Naval Observatory (USNO):
<a href="https://www.usno.navy.mil/USNO">https://www.usno.navy.mil/USNO</a>
and the material regarding "Systems of Time" at:
<a href="https://www.usno.navy.mil/USNO/time/master-clock/systems-of-time">https://www.usno.navy.mil/USNO/time/master-clock/systems-of-time</a>
which has descriptions of various different time systems including UT, UT1, and UTC.
In all methods of class Date
that accept or return year, month, date, hours, minutes, and seconds values, the following representations are used:
- A year y is represented by the integer y
- 1900
. - A month is represented by an integer from 0 to 11; 0 is January, 1 is February, and so forth; thus 11 is December.
- A date (day of month) is represented by an integer from 1 to 31 in the usual manner.
- An hour is represented by an integer from 0 to 23. Thus, the hour from midnight to 1 a.m. is hour 0, and the hour from noon to 1 p.m. is hour 12.
- A minute is represented by an integer from 0 to 59 in the usual manner.
- A second is represented by an integer from 0 to 61; the values 60 and 61 occur only for leap seconds and even then only in Java implementations that actually track leap seconds correctly. Because of the manner in which leap seconds are currently introduced, it is extremely unlikely that two leap seconds will occur in the same minute, but this specification follows the date and time conventions for ISO C.
In all cases, arguments given to methods for these purposes need not fall within the indicated ranges; for example, a date may be specified as January 32 and is interpreted as meaning February 1.

from
open static fun from(instant: Instant!): Date!
Obtains an instance of Date
from an Instant
object.
Instant
uses a precision of nanoseconds, whereas Date
uses a precision of milliseconds. The conversion will truncate any excess precision information as though the amount in nanoseconds was subject to integer division by one million.
Instant
can store points on the time-line further in the future and further in the past than Date
. In this scenario, this method will throw an exception.

For example, in Massachusetts, five time zones west of Greenwich:
new Date(96, 1, 14).getTimezoneOffset() returns 300
new Date(96, 5, 1).getTimezoneOffset() returns 240
This method produces the same result as if it computed:
(this.getTime() - UTC(this.getYear(), this.getMonth(), this.getDate(), this.getHours(), this.getMinutes(), this.getSeconds())) / (60 * 1000)

object, as interpreted in the local time zone.
Return | |
---|---|
Int |
the year represented by this date, minus 1900. |
See Also
hashCode
open fun hashCode(): Int
Returns a hash code value for this object. The result is the exclusive OR of the two halves of the primitive long
value returned by the Date.getTime
method. That is, the hash code is the value of the expression:
<code>(int)(this.getTime()^(this.getTime() >>> 32)) </code>
Return | |
---|---|
Int |
a hash code value for this object. |
parse
open static funparse(s: String!): Long
Deprecated: As of JDK version 1.1, replaced by DateFormat.parse(String s)
.
Attempts to interpret the string s
as a representation of a date and time. If the attempt is successful, the time indicated is returned represented as the distance, measured in milliseconds, of that time from the epoch (00:00:00 GMT on January 1, 1970). If the attempt fails, an IllegalArgumentException
is thrown.
It accepts many syntaxes; in particular, it recognizes the IETF standard date syntax: "Sat, 12 Aug 1995 13:30:00 GMT". It also understands the continental U.S. time-zone abbreviations, but for general use, a time-zone offset should be used: "Sat, 12 Aug 1995 13:30:00 GMT+0430" (4 hours, 30 minutes west of the Greenwich meridian). If no time zone is specified, the local time zone is assumed. GMT and UTC are considered equivalent.
The string s
is processed from left to right, looking for data of interest. Any material in s
that is within the ASCII parenthesis characters (
and )
is ignored. Parentheses may be nested. Otherwise, the only characters permitted within s
are these ASCII characters:
abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ 0123456789,+-:/
A consecutive sequence of decimal digits is treated as a decimal number:
- If a number is preceded by
+
or-
and a year has already been recognized, then the number is a time-zone offset. If the number is less than 24, it is an offset measured in hours. Otherwise, it is regarded as an offset in minutes, expressed in 24-hour time format without punctuation. A preceding-
means a westward offset. Time zone offsets are always relative to UTC (Greenwich). Thus, for example,-5
occurring in the string would mean "five hours west of Greenwich" and+0430
would mean "four hours and thirty minutes east of Greenwich." It is permitted for the string to specifyGMT
,UT
, orUTC
redundantly-for example,GMT-5
orutc+0430
. - The number is regarded as a year number if one of the following conditions is true:
- The number is equal to or greater than 70 and followed by a space, comma, slash, or end of string
- The number is less than 70, and both a month and a day of the month have already been recognized
java.text.SimpleDateFormat
. - If the number is followed by a colon, it is regarded as an hour, unless an hour has already been recognized, in which case it is regarded as a minute.
- If the number is followed by a slash, it is regarded as a month (it is decreased by 1 to produce a number in the range
0
to11
), unless a month has already been recognized, in which case it is regarded as a day of the month. - If the number is followed by whitespace, a comma, a hyphen, or end of string, then if an hour has been recognized but not a minute, it is regarded as a minute; otherwise, if a minute has been recognized but not a second, it is regarded as a second; otherwise, it is regarded as a day of the month.
A consecutive sequence of letters is regarded as a word and treated as follows:
- A word that matches
AM
, ignoring case, is ignored (but the parse fails if an hour has not been recognized or is less than1
or greater than12
). - A word that matches
PM
, ignoring case, adds12
to the hour (but the parse fails if an hour has not been recognized or is less than1
or greater than12
). - Any word that matches any prefix of
SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY
, orSATURDAY
, ignoring case, is ignored. For example,sat, Friday, TUE
, andThurs
are ignored. - Otherwise, any word that matches any prefix of
JANUARY, FEBRUARY, MARCH, APRIL, MAY, JUNE, JULY, AUGUST, SEPTEMBER, OCTOBER, NOVEMBER
, orDECEMBER
, ignoring case, and considering them in the order given here, is recognized as specifying a month and is converted to a number (0
to11
). For example,aug, Sept, april
, andNOV
are recognized as months. So isMa
, which is recognized asMARCH
, notMAY
. - Any word that matches
GMT, UT
, orUTC
, ignoring case, is treated as referring to UTC. - Any word that matches
EST, CST, MST
, orPST
, ignoring case, is recognized as referring to the time zone in North America that is five, six, seven, or eight hours west of Greenwich, respectively. Any word that matchesEDT, CDT, MDT
, orPDT
, ignoring case, is recognized as referring to the same time zone, respectively, during daylight saving time.
Once the entire string s has been scanned, it is converted to a time result in one of two ways. If a time zone or time-zone offset has been recognized, then the year, month, day of month, hour, minute, and second are interpreted in UTC and then the time-zone offset is applied. Otherwise, the year, month, day of month, hour, minute, and second are interpreted in the local time zone.
Parameters | |
---|---|
s |
String!: a string to be parsed as a date. |
Return | |
---|---|
Long |
the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by the string argument. |
Exceptions | |
---|---|
java.lang.IllegalArgumentException |
if s cannot be interpreted as a representation of a date and time. |
