I would like to build an EPG with the information retrieved by the TIF filter. But there is a problem, I am not sure that my current system time is really coherent with the time retrieved in the shedule entry.
Is it possible to aquire from the TIF or somewhere else a reference time clock coherent with start time and end time retrieved from the shedule entry???
Thx a lot!!

All times you get from the TIF should be in UTC so you should be able to just use the standard localisation functions to convert to local time.
