  Re: Getting a named DateTime::TimeZone from an offset

Bad example, as -8:00 is not PDT. PDT is -7:00, but so is MST. Even at
the same time, as some regions of the US don't observe summer time.

And that even ignores the rest of the world; for example, at this time
of year, -4:00 is known as AST, AMT, GYT, and BOT.

The only way in which you can ever do something like this is to restrict
yourself explicitly to a few timezones, in which case it isn't too hard
to iterate over them:

my $dt = DateTime::Format::ISO8601->parse_datetime( '20080701T000000-0400' );

print map { $_->short_name_for_datetime($dt) }
grep { $_->offset_for_datetime($dt) == $dt->offset }
map { DateTime::TimeZone->new(name => $_) }
qw/EST5EDT CST6CDT MST7MDT PST8PDT/;

Hello,

  ANNOUNCE: DateTime::Locale 0.42         


Author: Dave Rolsky
Date: Sep 12, 2008 09:27

0.42 2008-09-12

- Based on CLDR 1.6.1, but this has no changes in the data we use. I
just used 1.6.1 so people wouldn't ask me why I don't use 1.6.1 ;)

- In the switch to CLDR (back in 0.30), I accidentally dropped a
number of hard-coded aliases, notably for 'C'. These aliases have
been restored. Reported by Adam Kennedy. RT #39208.

- Generation of aliases based on the 3-letter ISO code for countries
is now based on the most recent version of ISO639.

  DateTime and Test::MockTime         


Author: Mark Pitchless
Date: Aug 28, 2008 02:26

Hello All,

For some reason using DateTime->now doesn't get effected by using the
Test::MockTime module to change the time. The Test module overrides
the time builtin, which seems to be what DateTime::now is using.

#!/usr/bin/perl
use DateTime;
use Test::MockTime qw/:all/;

my $start_time = time;
print "T: $start_time\n",
"DT:".DateTime->now()."\n";
print "----\n";
set_relative_time(6000);
my $rel_time = time;
print "T: $rel_time diff:".($rel_time-$start_time)."\n",
"DT:".DateTime->now()."\n";

  Contributing to DateTime::Event         


Author: Kristian Flint
Date: Aug 27, 2008 10:21

Hi everybody,

I've not been using DateTime for very long and got recommended it by our
hosting partners, really happy with it etc... But I've come across a
situation where I want to do something standardish with it and there
doesn't seem to be any provision for it. The reason I'm mailing the list
is that I'm amazed no-one has done this before which is leading me to a
suspicion that there's a good reason why!

So, what I want to do is get the the Bank Holidays for the UK and a few
other methods like 'is_this_a_bank_holiday( $dt )' or perhaps something
like 'number_of_working_days_in( $dt1, $dt2 )' to take into account
weekends. And so on as the project I'm working on requires.
Now, the reason I think this is possible is that looking at:
http://www.berr.gov.uk/employment/bank-public-holidays/index.html
The dates don't appear to be particularly random (they all have v.simple
rules) and the only dates I don't really understand, the easter ones,
I'm planning on using DateTime::Event::Easter to help me out.
