This doesn't tell me anything. Can you provide a code sample to demonstrate the problem?

How is your local time zone set on your system, and what is is set to?

I'm in London, and perl's localtime reports the time correctly, and ((localtime)[8]) is true. If you would like me to run a relevant command, please let me know, and I will report back.

Well, what I really want to know is the name of your system's time zone. This can be in a number of different spots, depending on your OS (and distro). Also, I'd like to see the code you're running,. Bug reports should always include code!

Well, this is Linux: CentOS to be precise, but it's still the same: lrwxrwxrwx 1 root root 33 Jun 16 16:03 /etc/localtime -> /usr/share/zoneinfo/Europe/London As before, this is correct: I am in London. When I run this perl: use DateTime; warn DateTime->now; # ->truncate( to => 'hour' ); warn scalar localtime; I get this output: 2006-08-03T12:04:03 at temp.pl line 3. Thu Aug 3 13:04:03 2006 at temp.pl line 4. Looks like you are not counting daylight-saving time.

now() returns a DateTeime object in the UTC time zone. If you want it to try to figure out your local time zone (really, whatever the system you're on thinks local is) then you need to do this: DateTime->now( time_zone => 'local' );

AAHH! Thanks! What really confused me is that it differs from the perl default, which is a very natural real-world default.... Thanks for your time on this! lee autarch@urth.org via RT wrote: Show quoted text
