Timezone info USA 2007

[mrn]

If the Daylight Savings Time option is enabled, the default in AIX is for the system time to move forward 1 hour (to DST) at 2:00am the first Sunday in April, and move back one hour (to Standard Time) at 2:00 a.m. on the last Sunday in October. Starting in 2007 this switch occurs on the second Sunday in March and ends the first Sunday in November. The default is hard coded and is not stored in any user accessible file. However, the date and time at which the switch to DST and ST occurs can be altered by the root user. To see if DST is enabled, echo $TZ; if the time zone variable ends in DT, DST is enabled.

"Whenever I dwell for any length of time on my own shortcomings, they gradually begin to seem mild, harmless, rather engaging little things, not at all like the staring defects in other people's characters."

I was wondering whether this applied only to the US myself, Mike.

I don't mind people who aren't what they seem. I just wish they'd make their mind up.

As far as I am aware this is not happening in the UK, or anywhere else in Europe. My TZ setting is

GMT0BST,M3.5.0,M10.5.0

which implies
[ol]
[li]I've a zero offset to GMT[/li]
[li]I change to BST on the fifth (read last) Sunday in the third month[/li]
[li]I change back to GMT on the fifth Sunday in the tenth month (last Sunday - loved the extra hour lie in!)[/li]

Thanks, Columb, that was my understanding too. Unfortunately, the kids' clocks didn't adjust in the same way last Sunday!
