Introduction to mktime function

The mktime() function returns the Unix timestamp of a date.

The argument always represents a GMT date, so is_dst has no effect on the result.

Grammar mktime(hour,minute,second,month,day,year,is_dst)

Parameter Description hour optional. Specified hours. minute is optional. Specified minutes. second is optional. Specifies seconds. month is optional. Specifies the numeric month. day is optional. Specify days. year is optional. Specified year. On some systems, legal values ​​are between 1901 - 2038. However, this limitation no longer exists in PHP 5. is_dst Optional. Set to 1 if the time is during Daylight Saving Time (DST), 0 otherwise, or -1 if unknown. As of 5.1.0, the is_dst parameter is deprecated. Therefore the new time zone handling features should be used.
