stMktime scans the given string and tries to read a date
and time from it. It understands various formats of date strings. The
following is a list of all valid formats, optional parts in brackets.
With no year given, the year defaults to the current year.
[19]93/01/05
This notation requires month and day represented by exactly two digits.
5.1.[19]93
This is the usual German notation.
5.1.
German notation referencing the current year.
A certain time, given together with the date must always have the
following form.
hours:minutes[:seconds]
Each of the fields must be an integer value within the proper range
(hours: 0-23, minutes and seconds: 0-59). Values below 10 may be
written as one digit numbers.
The time value may be placed anywhere in the date string: at the
beginning, at the end, or somewhere in the middle. Any amount of
whitespace may be given between a field of the time value and the
separating colon. The time is always considered to be local time.
stWriteTime generates a time string similar to asctime(3) from
its date argument.
