Tomasz Kamiński da15227f6c Implemented to/from_local functions for utc/tai/gps. ...

Implemented to_local and from_local functions for utc_clock,
tai_clock and gps_clock. For the tai/gps clock used this function
for defining the io - we delegate to serializing/parsing local
time.

The drwaback is that the local_time cannot properly represent
leap second in the UTC time, so separate serialization is needed.
