Tip: This function is identical to mktime() except the passed parameters represents a GMT date.

Syntax

gmmktime(hour,minute,second,month,day,year,is_dst);

Parameter	Description
hour	Optional. Specifies the hour
minute	Optional. Specifies the minute
second	Optional. Specifies the second
month	Optional. Specifies the month
day	Optional. Specifies the day
