Start with one of these `my $dt = DateTime::Format::ISO8601->parse_datetime( $datestr ); my $dt = DateTime::Format::DateParse->parse_datetime( $datestr ); my $dt = DateTime::Format::Flexible->parse_datetime( $datestr );` [download] Then finish with `$dt->set_time_zone( 'Country/City' ); print $dt->strftime( q[%a %b %e %H:%M:%S %Z %Y] ), "\n";` [download] or whatever	[reply] [d/l] [select]

My usual goto for dealing with time is DateTime. I don't know about the particular string format you are listing, but chances are there is something to do it in the DateTime::Format namespace, as dscussed in Parsing Dates. #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply]

Format is ISO 8601 ("T" is the separator between date & time; "z" is UTC time zone).	[reply]

DateTime is the canonical module for handling dates and times. DateTime::Format::ISO8601 and various other DateTime::Formats are handy for parsing textual dates and times. But you don't want to search for timezone abbreviations. Really, you don't. To take just one example, when you say EST do you mean UTC-5 (North America), UTC-3 (Brazil), or UTC+10 (Australia)?

how I can convert the time format such as "2012-10-02T12:34:08.94Z" to a UNIX format? You cannot do that because the Unix time format is an integer seconds from the "epoch time". ".94" hundredth's seconds is meaningless. A conversion from "2012-10-02 12:34:08Z" to a Unix time_t integer is possible. It is possible to track higher resolutions that one second. But you need a different data structure than a time_t value. I would look at Date::Time.	[reply]
