should elapse before dropping out of a timecode

Timecode Origin
When a project is created with timecode enabled, it
has an initial timecode origin of 01:00:00.00. This
defines the beginning of a 24-hour “timecode day” for
the project. If an operation hits the end of the timecode
day (e.g. 00:59:59.29, in this case), it is stopped.
Before recording audio into the project, the user can
modify the start/stop points of the timecode day to
correspond with the range of external timecode that
is expected to be used with the project. For example,
if the user is using 30 fps code, and sets the timecode
origin to 02:00:00.00, the timecode day will range
from [02:00:00.00 to 23:59:59.29] and then from
[00:00:00.00 to 01:59:59.29]. In this case, a recording
at 00:01:30.00 will be towards the end of the 24-hour
timecode day instead of near the beginning. This
makes “recording over midnight” possible in time of
day applications.

Timecode Offset
The HD-P2 can offset incoming timecode up to +/-12
hours during playback. This is useful when the user
wants to line up playback with a timecode source that
uses a different timecode range than that used to origi-
nally record the material into the project. An
