Time format

Time is normally shown and entered in h:m:s.f format, where h = hours, m = minutes, s = seconds, and f = fractional seconds. Places on the right may be omitted, in which case they default to zero. For example:

1one hour
1:2one hour + two minutes
1:2:3one hour + two minutes + three seconds
1:2:3.5one hour + two minutes + three and a half seconds
1:2:3.456789one hour + two minutes + three seconds + 456789 microseconds
0:2two minutes
0:0:3three seconds
0:0:0.4four hundred milliseconds

Time can alternatively be shown and entered in sample frames, by enabling the Show time in sample frames option. Sample frames are zero-origin, i.e. the first frame is frame zero.
