问题描述

如何在Perl中验证日期字符串?我想考虑闰年和时区。有人可能会按以下格式输入日期:

How can I validate date strings in Perl? I'd like to account for leap years and also time zones. Someone may enter dates in the following formats:


11/17/2008
11/17/2008 3pm
11/17/2008 12:01am
11/17/2008 12:01am EST
11/17/2008 12:01am CST


推荐答案

我使用这样的东西。使用你的日期....

I use DateTime::Format::DateManip for things like this. Using your dates....

use DateTime::Format::DateManip; 

my @dates = (
    '11/17/2008',
    '11/17/2008 3pm',
    '11/17/2008 12:01am',
    '11/17/2008 12:01am EST',
    '11/17/2008 12:01am CST',
);

for my $date ( @dates ) {
    my $dt = DateTime::Format::DateManip->parse_datetime( $date );
    die "Cannot parse date $date"  unless defined $dt;
    say $dt;
}

# no dies.. produced the following....
# => 2008-11-17T00:00:00
# => 2008-11-17T15:00:00
# => 2008-11-17T00:01:00
# => 2008-11-17T05:01:00
# => 2008-11-17T06:01:00
