如何将datetime转换为不同的格式？ [perl] [英] How do I convert datetime to a different format? [perl]

问题描述

需要帮助解析日期时间戳，并按日期和时间分割。

Need help parsing the datetime stamp and splitting it up by date and time.

use strict;
use warnings;
use Time::Piece;

my $string = "05:57:03 08/31/10 MDT";

print $string,"\n";

my $time = Time::Piece->strptime($string, "%H:%M:%S");
my $date = Time::Piece->strptime($string, "%Y/%m/%d");

print $time,$date,"\n";

谢谢！ 此外，我如何知道这是使用代码的星期几？

推荐答案

能够使用如下代码：

my $t = Time::Piece->strptime($string, "%H:%M:%S %m/%d/%y %Z");

但是，至少在我的系统上，我必须将时区MST更改为GMT，以将其更改为比赛;如果我把它留在你的例子中，我会收到一个错误：

However, on my system at least, I have to change the time zone MST to GMT for it to match; if I leave it as in your example, I get an error:

Perl> my $t = Time::Piece->strptime("05:57:03 08/31/10 DST", "%H:%M:%S %m/%d/%y %Z");
[!] Runtime error: Error parsing time at /usr/local/lib/perl/5.10.0/Time/Piece.pm line 469.

如果它适用于你，你会有一个Time :: Piece对象，你可以在其上调用eg $ t-> day_of_week 作为一个数字， $ t-> day 'Tue'或 $ t-> fullday 'Tuesday'。

If it works for you, though, you'll have a Time::Piece object, on which you can call e.g. $t->day_of_week for the day of the week as a number, $t->day for e.g. 'Tue', or $t->fullday for e.g. 'Tuesday'.

请参阅 Time :: Piece ，了解您可以致电的方法。

See the documentation for Time::Piece for details on the methods you can call.
