-;# timelocal.pl
-;#
-;# Usage:
-;# $time = timelocal($sec,$min,$hours,$mday,$mon,$year,$junk,$junk,$isdst);
-;# $time = timegm($sec,$min,$hours,$mday,$mon,$year);
-
-;# These routines are quite efficient and yet are always guaranteed to agree
-;# with localtime() and gmtime(). We manage this by caching the start times
-;# of any months we've seen before. If we know the start time of the month,
-;# we can always calculate any time within the month. The start times
-;# themselves are guessed by successive approximation starting at the
-;# current time, since most dates seen in practice are close to the
-;# current date. Unlike algorithms that do a binary search (calling gmtime
-;# once for each bit of the time value, resulting in 32 calls), this algorithm
-;# calls it at most 6 times, and usually only once or twice. If you hit
-;# the month cache, of course, it doesn't call it at all.
-
-;# timelocal is implemented using the same cache. We just assume that we're
-;# translating a GMT time, and then fudge it when we're done for the timezone
-;# and daylight savings arguments. The timezone is determined by examining
-;# the result of localtime(0) when the package is initialized. The daylight
-;# savings offset is currently assumed to be one hour.
