I have a problem on using time, please advise. But in short, how can I force Perl to PERMANENTLY consider I am working in GMT+0 location? ( besides from change my system timezone )
I am in location GMT+8, and work with Win32. Then, when I call localtime(0), It's actually point to Jan 1, 1970, 08:00 in local time.
In some cases, I'll use gmtime($random_second) to have the time data array which based from Jan 1, 1970, 00:00. (eg. for time compare )
But in other often cases, I have to use know system time ( eg. for logging )I'll call localtime(time).
However, when things are mixed together to run, I am really very headache to decide when to localtime and when to gmtime, in a same package.
Anyway, perhaps I cannot express well either from above, but what concerns me is simply the question asked at the beginning. I just want a constant way that I can relay on, without want to check against which timezone I am in, but always correct.
UPDATE at Apr 09, 01:32 GMT+8
After server replies, seems my given example has side tracked monks around. Deep sorry about this. I would take chance to highlight that, my question is
"how can I force Perl to PERMANENTLY consider I am working in GMT+0 location?" This means and implies, gmtime and locatime will return me the same result; OR same effect as I change my system timezone to GMT+0.
