timezone: fix issues with timezone detection of current logic.

- it was reported that in certain timezones e.g `US/Central` the generated offset was +19:00 which
is incorrect and should be -05:00.
- we now use a special library for detection of local timezone and use logic of pytz to calculate the offset
- fixes  #5371
