Explanation: start and stop dates

Format of start/stop dates: YYYY.MM.DD_hh:mm that means: a) four digit year — for example: 1979, 2015; b) two digit month number with leading zero — for example: 01, 12; c) two digit day number in the month — for example: 02, 27; d) underscore; e) two digit hour number with leading zero — for example 04, 21; f) two digit minute number with leading zero — for example 05, 58. Fields with hour and minute can be omitted, which is equivalent to _00:00.

Example of dates:

2015.05.30_22:57 — May 30, 2015, 22 hours, 57 minutes;
1979.12.08            — December 08, 1979, 00 hours, 00 minutes

Stop date should be equal or after the start date.
