Free and open source software (FOSS) is only beginning to find a foothold in computer science departments in North America. FOSS tools may be used in teaching or be the subject of research or special committees, but few departments include courses that introduce students to the FOSS community. As a result, when North Carolina State University created a FOSS graduate course in the 2008 spring semester, it turned to Red Hat to find an instructor with a suitable background of FOSS involvement and university teaching experience. Community manager Greg DeKoenigsberg recommended performance tools engineer Will Cohen, who now looks back at the experience with an eye to how what he and his students learned might help other instructors.
Hello All,
I am a learner in C++. I was testing my inheritance knowledge with following piece of code.

Date::Parse(3) User Contributed Perl Documentation Date::Parse(3)NAME
Date::Parse - Parse date strings into time values
SYNOPSIS
use Date::Parse;
$time = str2time($date);
($ss,$mm,$hh,$day,$month,$year,$zone) = strptime($date);
DESCRIPTION
"Date::Parse" provides two routines for parsing date strings into time values.
str2time(DATE [, ZONE])
"str2time" parses "DATE" and returns a unix time value, or undef upon failure. "ZONE", if given, specifies the timezone to assume when
parsing if the date string does not specify a timezone.
strptime(DATE [, ZONE])
"strptime" takes the same arguments as str2time but returns an array of values "($ss,$mm,$hh,$day,$month,$year,$zone)". Elements are
only defined if they could be extracted from the date string. The $zone element is the timezone offset in seconds from GMT. An empty
array is returned upon failure.
MULTI-LANGUAGE SUPPORT
Date::Parse is capable of parsing dates in several languages, these include English, French, German and Italian.
$lang = Date::Language->new('German');
$lang->str2time("25 Jun 1996 21:09:55 +0100");
EXAMPLE DATES
Below is a sample list of dates that are known to be parsable with Date::Parse
1995:01:24T09:08:17.1823213 ISO-8601
1995-01-24T09:08:17.1823213

21-dec 17:05

21/dec/93 17:05
1999 10:02:18 "GMT"
16 Nov 94 22:28:20 PST
LIMITATION
Date::Parse uses Time::Local internally, so is limited to only parsing dates which result in valid values for Time::Local::timelocal. This
generally means dates between 1901-12-17 00:00:00 GMT and 2038-01-16 23:59:59 GMT
BUGS
When both the month and the date are specified in the date as numbers they are always parsed assuming that the month number comes before
the date. This is the usual format used in American dates.
The reason why it is like this and not dynamic is that it must be deterministic. Several people have suggested using the current locale,
but this will not work as the date being parsed may not be in the format of the current locale.
My plans to address this, which will be in a future release, is to allow the programmer to state what order they want these values parsed
in.
