To switch from 2 different timebases, the following calculation is
defined:
ln = from_time_base_nom*to_time_base_denom
ln = from_time_base_num*to_time_base_denom
sn = from_timestamp
d1 = from_time_base_denom
d2 = to_time_base_nom
d2 = to_time_base_num
timestamp = (ln/d1*sn + ln%d1*sn/d1)/d2
Note: this calculation MUST be done with unsigned 64 bit integers, and
is equivalent to (ln*sn)/(d1*d2) but this would require a 96bit integer
