[AutoTimer] auto resolve conflict offset time begin/end (30 sec)

example - for sake of simplicity, usage is on a single tuner receiver ,
no overlaps in the timers
Timer A = 19:00 to 19:30
Timer B = 19:30 to 20:00
The above will always result in a clash because one ends at 19:30 and
the other also starts at 19:30
End 19:30:00.000 and start at 19:30:30.000 should work, but that is not
currently possible.
