Do you know any Pascal lib to parse strings to convert in date/time values?
The user is supposed to type human-friendly values like:
- "day" => trunc(now)
- "day-2" => trunc(now-2)
- "week" => trunc(now-7)
- "yesterday" => trunc(now-1)
- etc...
But they could type even their computer date format or ISO as well.
A lib in C, but very complex:
- https://github.com/gagern/gnulib/blob/master/lib/parse-datetime.y
I would like to start with something simpler, if possible. Thank you.
I don't know a specific library that fulfills your needs, but maybe you can
build something atop of FpExprPars:

At least according to the source it also supports datetime handling.
It does, it's used (amongst other things) in the reporting engine;
