Date Help

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

I need some help with reformatting dates, I got a script that gets results for the Whois database and I need to check the expiration dates. The dates or formatted in different ways. Here is a list of expiration dates

Now my question. Is there a way or program that can distinguish and reformat them.

Some modules understand a number of date formats. I think Date::Calc, Date::Manip and Date::Parse are among them.	[reply]
Re: Date Help by wazzuteke (Hermit) on Jan 04, 2006 at 19:29 UTC
I've found the module `Date::Calc` to be usefull in such situations. Check out CPAN for more info on it. At a first glance, it looks as though you might want one of two functions that are pre-built into the mod. I'd recommend: `use Date::Calc qw( Decode_Date_EU Decode_Date_US );` [download] For a good portion of the dates, although there may be more that would be better suited for you to use. ---hA\|\|ta---- `print map{$_.' '}grep{/\w+/}@{[reverse(qw{Perl Code})]} or die while ( 'trying' );`	[reply] [d/l] [select]

Is there a way or program that can distinguish and reformat them. To distinguish, you may use regular expressions as explained in `perldoc perlre` or `perlrequick`. To reformat them, see the answers to a question asked earlier today: Best way to compare date strings. Cheers, Sören	[reply]

This module looks very interesting: Time::Format	[reply]
Re: Date Help by ambrus (Abbot) on Jan 05, 2006 at 12:08 UTC
The CPAN module Date::Manip parses most of these dates, but there are some (namely those of format mm-dd-yyyy and `2014-05-30 PST (0)`) which it can't parse. Here's an example, of course you can use any other output format than the `"%c"` I'm using here. use warnings; use Date::Manip; while (<DATA>) { if (/(.*: )(.+)/ and defined($d = UnixDate($2, "%c"))) { print $1, $d, "\n"; } else { print $_; } } __DATA__ xmas.com : 08-Nov-2007 ---------------------------------------------------------------------- +--------- jacket.com : 30-Jul-2006. ---------------------------------------------------------------------- +--------- shows.com : 2006-12-20 ---------------------------------------------------------------------- +--------- item.com : 22-Aug-2009. ---------------------------------------------------------------------- +--------- ...
