__pmMktime
is very similar to
mktime(3),
except the timezone used is the current ``reporting timezone'' (rather than the
default
TZ
environment variable scheme).
Like
mktime(3)
the time to be converted is passed via
timeptr,
and
the function result
contains the calendar time (the number of seconds since 00:00:00 UTC,
January 1, 1970).
The default current reporting timezone is as defined by the
TZ
environment variable, so
__pmMktime
and
mktime(3)
will initially produce similar conversions.
