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.
[Tue] Jan 5[,] [19]93
This includes the standard asctime(3) format.
Jan 5 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.
