Description
This tag takes in a string and parses out time components for a duration. It then returns the duration it found. White space, time component order, and extraneous text are ignored. Only the first found instance of a time component is used.
Sample Usage
lsd_string_toduration('1d 17h 45m 22s');
lsd_string_toduration('Duration is 17h 1 d45 m22s');
lsd_string_toduration('Duration is 1 Day 17 Hours 45 Minutes and 22 Seconds');
lsd_string_toduration('17h 1 d45 m22s 0d0h0m0s');
