Maked clock_time_conversion as const and used alias.

Browse Source 
Marked operator() of all supplied clock_time_conversion overload
as const.
Changed input type to sys_time/utc_time alias when possible.
Used consitient nomencalture: st for sys_time, ut for utc_time
and tp for time in different clock.
