Date class in Yate's Javascript implementation.
[edit] Constructor
- new Date()
- new Date(value)
- new Date(str)
- new Date(year, month [, day, hour, minute, second, milliseconds])
Where:
Parameters:
- value Integer value representing the number of milliseconds since 1 January 1970 00:00:00 UTC (Unix Epoch).
- str String describing the date. See format below. Handled as Unix Epoch time.
- year Integer value representing the year. Values from 0 to 99 map to the years 1900 to 1999.
- month Integer value representing the month, beginning with 0 for January to 11 for December.
- day Integer value representing the day of the month.
- hour Integer value representing the hour of the day.
- minute Integer value representing the minute segment of a time.
- second Integer value representing the second segment of a time.
- milliseconds Integer value representing the milliseconds segment of a time.
If no arguments are provided, the constructor creates a JavaScript Date object for the current date and time according to system settings.
String format:
yyyy-mm-ddThh:mm:ss[.SEC-FRAC]Z
yyyy-mm-ddThh:mm:ss[.SEC-FRAC]{+/-}hh:mm
Notes:
T and Z are case insensitive (t and z are may be given).
SEC-FRAC: Optional second fractions (milliseconds).
The second format indicates a timezone (hours:minutes) offset. Held time will be increased or decreased with given timezone offset value.
Examples:
new Date("2010-01-01T00:10:01Z");
new Date("2010-01-01T00:10:01.500Z");
new Date("2010-01-01T00:10:01+00:03");
new Date("2010-01-01T00:10:01.500+00:03");
new Date("2010-01-01T00:10:01.500-00:03");
The following lead to constructor failure (return null):
new Date("1010-01-01T00:10:01Z"); // Date before Unix Epoch
new Date("1970-01-01T00:10:01-23:00"); // Date before Unix Epoch after applying timezone offset
[edit] Static methods
- Date.now()
Static method Date.now() returns Integer value representing the number of milliseconds since 1 January 1970 00:00:00 UTC (Unix Epoch)
- UTC(year, month [, day, [,hour, [,minute, [,second, [,milliseconds]]]]])
Build Unix Epoch time from components.
Parameters:
- year Integer value representing the year. Values from 0 to 99 map to the years 1900 to 1999.
- month Integer value representing the month, beginning with 0 for January to 11 for December.
- day Integer value representing the day of the month.
- hour Integer value representing the hour of the day.
- minute Integer value representing the minute segment of a time.
- second Integer value representing the second segment of a time.
- milliseconds Integer value representing the milliseconds segment of a time.
Return:
Success: integer value representing the number of milliseconds since 1 January 1970 00:00:00 UTC (Unix Epoch).
Failure: NaN (invalid parameters).
[edit] Methods
- getDate
Returns the day of the month (1-31) for the specified date according to local time.
- getDay
Returns the day of the week (0-6) for the specified date according to local time.
- getFullYear
Returns the year (4 digits for 4-digit years) of the specified date according to local time.
- getHours
Returns the hour (0-23) in the specified date according to local time.
- getMilliseconds
Returns the milliseconds (0-999) in the specified date according to local time.
- getMinutes
Returns the minutes (0-59) in the specified date according to local time.
- getMonth
Returns the month (0-11) in the specified date according to local time.
- getSeconds
Returns the seconds (0-59) in the specified date according to local time.
- getTime
Returns the numeric value of the specified date as the number of milliseconds since January 1, 1970, 00:00:00 UTC (negative for prior times).
- getTimezoneOffset
Returns the time-zone offset in minutes for the current locale.
- getUTCDate
Returns the day (date) of the month (1-31) in the specified date according to universal time.
- getUTCDay
Returns the day of the week (0-6) in the specified date according to universal time.
- getUTCFullYear
Returns the year (4 digits for 4-digit years) in the specified date according to universal time.
- getUTCHours
Returns the hours (0-23) in the specified date according to universal time.
- getUTCMilliseconds
Returns the milliseconds (0-999) in the specified date according to universal time.
- getUTCMinutes
Returns the minutes (0-59) in the specified date according to universal time.
- getUTCMonth
Returns the month (0-11) in the specified date according to universal time.
- getUTCSeconds
Returns the seconds (0-59) in the specified date according to universal time.
- toJSON()
Returns formatted string with date description.
Example:
var d = new Date(1262304601900); var s = d.toJSON(); // s contents: 2010-01-01T00:10:01.900Z
