[Tutor] Time - sum/difference

[Jonas Melian]

I would get the local time of a country, using UTC (Universal Time 
Coordinated) and DST (Daylight SavingTime) of that country.

An example, utc time -02:30 and dst +1 :

country_utc = datetime.time(2,30)
isUTCNegative = True
dst = datetime.time(1,0)

Now I would the difference of both times.
-02:30 + 01:00 -> -01:30

Is possible get sum/difference of time values? How?

Thanks in advance
