How to Parse an RFC 822 style date with Time::Piece?

I'm using the excellent Time::Piece module and it is working well for me except for one thing. I need to parse an RFC 822 style Date with strptime. What I want is something like:

$date = Time::Piece->strptime($msg->date, "%a, %d %b %Y %H:%M:%S %z");
[download]

but apparently %z is a GNUism and not supported by the module. So is there an alternate format string I can use instead? Or if worst comes to worst, is there another module that can convert an RFC 822 date into a comparable quantity?

In the simplest case, you can use HTTP::Date. If it can parse such dates (I think so, but not sure off the top of my head), a really comprehensive solution written to offer speed and versatility would be Date::Calc - it's become my favourite date/time module. Makeshifts last the longest.	[reply]

Date::Manip should parse this. It's slower than most (all Perl) but I found that it parses almost anything you can throw at it.	[reply]

Even its author says (in the POD even, IIRC) that you should probably try to make something else work before you go for Date::Manip though. It's a great module when you are trying to cope with sloppy date/time descriptions or want to allow them, but it tries to be so smart it really shouldn't be used if you don't really need its capabilities. Makeshifts last the longest.	[reply]

I've seen that comment in the Date::Manip docs. But it's so easy to use and just gets the job done. If I'm concerned with performance, I'll have to look into some of the many other date and time modules. But I have lots of stuff (for example cron jobs) where I'll gladly trade some CPU cycles to save a few of my cycles.	[reply]

Thanks to all those who replied. Sorry for not getting back to you but I didn't get a chance to work on this problem again until today. I uploaded the script here so you can see what I was doing. I'd appreciate any suggestions for speeding it up. For parsing the dates, I took aristotle's suggestion and used HTTP:Date. It was perfect for my needs. -- જલધર	[reply]
