DateTime->now problem

Grimey has asked for the wisdom of the Perl Monks concerning the following question:

#!/usr/bin/perl -w

use strict;
use DateTime;

my $now = DateTime->now;
[download]

-------------------------------------------------

When I attempt to run the program I get to following:

$ perl perltest.pl 'regex' validation parameter for 'DateTime::from_epoch must be a string or qr// regex at /usr/local/lib64/perl5/DateTime.pm line 486 DateTime::from_epoch(undef, 'epoch', 1301690690) called at /usr/local/lib64/perl5/DateTime.pm line 511 DateTime::now('DateTime') called at perltest.pl line 6

----------------------------------------------------------

I attempted to look at the DateTime.pm file, but I couldn't see the problem in from_epoch().

I have used this module on a different server before with success. On the new server (redhat 6.0) DateTime installed from CPAN without a fuss, but I can't use it.

Please let me know if I have done anything incorrectly, I am a first time poster here and would be grateful for any help as googling this issue has brought information.

This is perl 5, version 12, subversion 3 (v5.12.3) built for x86_64-linux-thread-multi

DateTime is up to date (0.66).

perl -le'use Params::Validate; print Params::Validate->VERSION'

0.95

Do you get the error when you run the following? use strict; use warnings; use Params::Validate qw( validate validate_pos UNDEF SCALAR BOOLEAN HASHREF OBJECT ); print($INC{'Params/ValidateXS.pm'} ?'XS':'PP',"\n"); my $spec = { epoch => { regex => qr/^-?(?:\d+(?:\.\d)?\|\.\d+)$/ }, locale => { type => SCALAR \| OBJECT, optional => 1 }, language => { type => SCALAR \| OBJECT, optional => 1 }, time_zone => { type => SCALAR \| OBJECT, optional => 1 }, formatter => { type => SCALAR \| OBJECT, can => 'format_datetime', optional => 1 }, }; validate( @{[ 'epoch', 1301690690 ]}, $spec ); [download] Does it say "PP" or "XS"? Update*: Added PP/XS bit.	[reply] [d/l]

What's the output of the following? use strict; use warnings; use Params::Validate qw( validate validate_pos UNDEF SCALAR BOOLEAN HASHREF OBJECT ); print($INC{'Params/ValidateXS.pm'} ?'XS':'PP',"\n"); my $spec = { epoch => { regex => qr/^-?(?:\d+(?:\.\d*)?\|\.\d+)$/ }, locale => { type => SCALAR \| OBJECT, optional => 1 }, language => { type => SCALAR \| OBJECT, optional => 1 }, time_zone => { type => SCALAR \| OBJECT, optional => 1 }, formatter => { type => SCALAR \| OBJECT, can => 'format_datetime', optional => 1 }, }; use Devel::Peek; Dump($spec->{epoch}{regex}); my $x = $spec->{epoch}{regex}; Dump($spec->{epoch}{regex}); validate( @{[ 'epoch', 1301690690 ]}, $spec ); [download]	[reply] [d/l]

Digging into the XS. In the meantime, you might want to try reinstalling Params::Validate.	[reply]

You're too fast! I added a check to see which of P::V's backends you use.	[reply]

Can you post more code? Where are you calling `from_epoch`? Also, please see Writeup Formatting Tips.	[reply] [d/l]

It might help to know your version of Perl and of Data::Time; there's certainly nothing wrong with your code (except your failure to follow the formatting guidelines above and below the text box where you entered you question) under any win32 or Linux immediately available to me (w2k, XP, Vista, Ubuntu 10.04/Gnome or (ancient RHs).

Well, I'd say there could very well be a missing `time_zone => 'local'` argument, but it wouldn't cause the error. I would also like to know the version Params::Validate he has installed. The version can be obtained using `perl -v \| grep version perl -le'use DateTime; print DateTime->VERSION' perl -le'use Params::Validate; print Params::Validate->VERSION'` [download]	[reply] [d/l] [select]

DateTime works fine for me. `(undef, epoch, 1301690690)` isn't the correct way to do it. I did this using now and from_epoch: `#!/usr/bin/perl use strict; use warnings; use DateTime; my $dt = DateTime->now( 'time_zone' => 'local' ) ->set_time_zone( 'floating' ); print $dt, "\n"; $dt = DateTime->from_epoch( 'epoch' => 1301690690 ); print $dt, "\n";` [download]	[reply] [d/l] [select]
