Re: Data::Juxtapose 0.01 [Re: patch: DateTime::TimeZone PP redundant structures]
The basic format seems good. I'm not sure about using weak_ref, though -- what if an object or structure falls out of scope, yet there's still a key in the data registry? If another ref comes along whose fingerprint matches that key, does it end up getting replaced with undef ? (I'm kind of sleepy at the moment, so I could be misreading the code). Also, as originally implemented in the context of DateTime::TimeZone, I was using class structures and class methods. You've moved it into object mode, which is fine, but I'm curious as to how you utilize the shared object. I'm assuming it's a single object in the DT::TZ base class? Cheers, Matt

I had a reason why I did that, but I can't seem to come up with a good reason now. Hmm. I suppose it won't hurt to *not* have it, I guess I can just remove it.

Yeah, that's what I was planning to do. just hold a class variable that points to a D::J object. --d
RE: Error Message using Time::Local
Hi Behzad, (snipped) CASE 1 -- use Time::Local 'timelocal_nocheck'; use Time::Local qw(timelocal_nocheck timelocal); Should fix that :-) CASE 2 -- Use Time::Local; Use of uninitialized value in integer multiplication (*) at C:/Perl/lib/Time/Local.pm line 76 (#1) Day '31' out of range 1..30 at c:\myCode.pl 98 At C:/Perl/lib/Time/Local.pm line 116 Time::Local::timegm called at C:/Perl/lib/Time/Local/pm line 153 Time::Local::timelocal(0, 0, 0, 31, 08, 2004) called at C:\myCode.pl line 98 From the Time::Local Docs It is worth drawing particular attention to the expected ranges for the values provided. The value for the day of the month is the actual day (ie 1..31), while the month is the number of months since January (0..11). This is consistent with the values returned from localtime() and gmtime(). So, If you wanted a date of Aug 31, 2004 the call to timelocal Should be: my $time = timelocal(0, 0, 0, 31, 7, 2004); And to confirm use strict; use DateTime; use warnings; use Time::Local qw(timelocal_nocheck timelocal); my $time = timelocal(0, 0, 0, 31, 7, 2004); my $dt = DateTime-from_epoch( epoch = $time ); print $dt-mdy; prints: D:\scriptsme.pl 08-31-2004 I hope this helps Ron Hill
Date time Issue
Hi, I've an issue storing a datetime value in oracle db from a perl module. Below is the issue, The string date has a value as 'Jul 18, 2005 7:45:17 PM' and when I directly store it to an oracle database field datetime, it's storing as 07/18/2005 07:45:17 AM. Not sure why it's converted to AM instead PM. Could you please let me know if I have to do anything (any conversion) before I store it there. Thanks, Joseph

Not sure why it's converted to AM instead PM. I don't recognise the format, and anything other than ISO datetimes can be confusing so I'd use the swiss-army-parser to convert from your existing format to an ISO datetime: DateTime.pm. Over the past couple of years we've developed quite a tool suite, and in this case I'd use DateTime::Format::Strptime to parse the existing code. use DateTime::Format::Strptime; my $parser = DateTime::Format::Strptime-new( pattern = '%b %d, %Y %I:%M:%S %p' ); $converted_to_iso = $parser-parse_datetime( $original )-datetime; # or Procedural: use DateTime::Format::Strptime qw/strptime strftime/; $converted_to_iso = strftime( '%Y-%m-%d %H:%M:%S', strptime( '%b %d, %Y %I:%M:%S %p', $original ) );
