GMMKTIME(3) 1 GMMKTIME(3)
gmmktime - Get Unix timestamp for a GMT date
SYNOPSIS
int gmmktime ([int $hour = gmdate("H")], [int $minute = gmdate("i")], [int $second = gmdate("s")], [int $month = gmdate("n")], [int
$day = gmdate("j")], [int $year = gmdate("Y")], [int $is_dst = -1])
DESCRIPTION
Identical to mktime(3) except the passed parameters represents a GMT date. gmmktime(3) internally uses mktime(3) so only times valid in
derived local time can be used.
Like mktime(3), arguments may be left out in order from right to left, with any omitted arguments being set to the current corresponding
GMT value.
PARAMETERS
o $hour
- The number of the hour relative to the start of the day determined by $month, $day and $year. Negative values reference the hour
before midnight of the day in question. Values greater than 23 reference the appropriate hour in the following day(s).
o $minute
- The number of the minute relative to the start of the $hour. Negative values reference the minute in the previous hour. Values
greater than 59 reference the appropriate minute in the following hour(s).
o $second
- The number of seconds relative to the start of the $minute. Negative values reference the second in the previous minute. Values
greater than 59 reference the appropriate second in the following minute(s).
o $month
- The number of the month relative to the end of the previous year. Values 1 to 12 reference the normal calendar months of the
year in question. Values less than 1 (including negative values) reference the months in the previous year in reverse order, so 0
is December, -1 is November, etc. Values greater than 12 reference the appropriate month in the following year(s).
o $day
- The number of the day relative to the end of the previous month. Values 1 to 28, 29, 30 or 31 (depending upon the month) refer-
ence the normal days in the relevant month. Values less than 1 (including negative values) reference the days in the previous
month, so 0 is the last day of the previous month, -1 is the day before that, etc. Values greater than the number of days in the
relevant month reference the appropriate day in the following month(s).
o $year
- The year
o $is_dst
- Parameters always represent a GMT date so $is_dst doesn't influence the result.
Note
This parameter has been removed in PHP 7.0.0.
RETURN VALUES
Returns a integer Unix timestamp.
