Gmdate returns the time difference between the current time and GMT.
Syntax: string gmdate (string format, int timestamp );
Return Value: String
Function Type: time and date
This function is similar to the date () function. The difference is that this function returns the Time after the Time difference from the Greenwich Mean Time (GMT ).
Example
Echo date ("M d y h: I: s", mktime ));
Echo gmdate ("M d y h: I: s", mktime ));
?>
If the machine running this example is in Finland (Finland, GMT + 0200), the returned result is:
Jan 01 00:00:00 1998
Dec 31 1997 22:00:00
Refer to date () mktime () gmmktime ()
Easter_date is used to calculate the Easter date.
Syntax: int easter_date (int [year]);
Return Value: integer
Function Type: time and date
Description: if a year is input, the Easter date of the year is returned in UNIX time stamp format. If the year is not input, the date of the year is calculated. Value? Note that the input year must be between 1970 a.m. and 2037 a.m.; otherwise, it cannot be calculated.
Example
Echo date ("M-d-Y", easter_date (1999 ));
Echo date ("M-d-Y", easter_date (2000 ));
Echo date ("M-d-Y", easter_date (2001 ));
?>
The returned result is
Apr-04-1999
Apr-23-2000

Easter_days is used to calculate the number of days between Easter and January 1, lunar March 21.
Syntax: int easter_days (int [year]);
Return Value: integer
Function Type: time and date
Description: if a year is input, the number of days between Easter and January 1, March 21 is calculated. If the year is not input, the current year is used. This function can be used to replace the issue that cannot be calculated beyond the range easter_date () 1970-2037.
Example
Echo easter_days (1999 );
Echo easter_days (1492 );
Echo easter_days (1913 );
?>
The returned result is:
14 (4/4)
32 (4/22)
2 (3/23)
Refer to easter_date ()
Mktime gets UNIX timestamps.
Syntax: int mktime (int hour, int minute, int second, int month, int day, int year );
Return Value: integer
Function Type: time and date
Description: enter a time to return a long integer of UNIX timestamps.
Example
Echo date ("M-d-Y", mktime ));
Echo date ("M-d-Y", mktime ));
Echo date ("M-d-Y", mktime ));
?>
Refer to date () time ()
Gmmktime obtains the Greenwich Mean Time of UNIX timestamps.
Syntax: int gmmktime (int hour, int minute, int second, int month, int day, int year );
Return Value: integer
Function Type: time and date
Description: enter a time to return a long integer of the UNIX Greenwich Mean Time Stamp.
