I should elaborate on my first point and ask additionally if a call to:
mktime(12, 0, 0, 5, 10, 2007);
for example, will always return the exact same timestamp in either GMT
or UTC timezone and vice versa, i.e. 1 timestamp resulting in the exact
same 12:00:00 readout via date() whether GMT or UTC. Thanks.
