Is this a homework assignment?

What have you tried to solve this problem?

Do these date and time stamps appear on lines by themselves? Or at the start of lines? Or at a fixed location other than the start of a line? If not, how can the date and time stamps be uniquely identified as distinct from other text that might appear in your data?

Is this data contained in a text file? What is the format of data in your input file other than the date and time strings?

Is this a stand-alone project, or is other processing going to be done to your data at the same time? If other processing is being done, what tools are being used to do the other processing?

Your sample data and the format you showed us for your sample data is inconsistent. Is there one space between the day and the year as shown in:
Code:
Mon DD YYYY hh:mi:ss AM/PM

Or are there two spaces as shown in:
Code:
Jan 01  2015 11:00:00 PM

?

NAME
Email::Date::Format - produce RFC 2822 date strings SYNOPSIS
use Email::Date::Format qw(email_date); my $header = email_date($date->epoch); Email::Simple->create( header => [ Date => $header, ], body => '...', ); DESCRIPTION
This module provides a simple means for generating an RFC 2822 compliant datetime string. (In case you care, they're not RFC 822 dates, because they use a four digit year, which is not allowed in RFC 822.) FUNCTIONS email_date my $date = email_date; # now my $date = email_date( time - 60*60 ); # one hour ago "email_date" accepts an epoch value, such as the one returned by "time". It returns a string representing the date and time of the input, as specified in RFC 2822. If no input value is provided, the current value of "time" is used. "format_date" is exported only if requested. email_gmdate my $date = email_gmdate; "email_gmdate" is identical to "email_date", but it will return a string indicating the time in Greenwich Mean Time, rather than local time. "format_gmdate" is exported only if requested. PERL EMAIL PROJECT
