Efficiently compute time from local and GMT time

The POSIX standard provides three functions for converting between integer epoch values and 6-component “broken-down” time representations. localtime and gmtime convert an epoch into the 6 components of seconds, minutes, hours, day of month, month and year, in either local timezone or UTC. The mktime function converts a local broken-down time into an epoch value. However, POSIX does not provide a UTC version of this.

This module provides a function timegm which has this ability.
