Title: (SOLVED) Time Zones
Post by: nickjf20 on June 05, 2011, 12:52:00 PM

Hi,

I'm trying to get timezones to work, but they seem to do the opposite of what I add to the bootcodes.

This is my bootcode;

tz=UTC+5DST,M3.3.0/2.M11M1M0/2

and my 'hwclock' (in UTC)

'12:30 ...'

and 'date'

'... 7:30 ... '

DST works fine for UTC+0, but seems to have no effect on any variation.

Thanks.

Bcause UTC is the timezone, not the reference.
For example: I am in Central Standard Time (US) which is 6 hours behind UTC, so my timzone would be
CST6CDT

Ahh, so the reference is the three letters which denote the timezone rather than the difference between the local time and GMT?

Thats interesting. Is there a list of the timezone denotations around ? I need to work them into this script

Brilliant. Thanks for the link !

I don't know what the general consensus around here is for solved threads, so I'll just add (solved) to the title.

Thanks,

Nick
