And many programs might actually prefer using 00:00:00:00 as a start for clips that don’t have timecode as some programs (as seen here with this example) interpret timecode in different ways. Some programs will use creation date and timestamp and write it out to HH:MM:SS:00 always ending in :00 while others also interpret a frame count. Depending on program and frame rate, you could be off by 29 frames. Not to mention proper calculations of 23.976*(100/1000) and 24*(1000/1001).
Another NLE when interpreting timecode does not take into account UTC, so if shooting before or daylight savings time and conforming afterwards will cause a 1 hour mismatch. Depending on schedules, applications used and such, a mix and match of any of these methods will cause headaches.
That is why 00:00:00:00 can actually be a nice method with no interpretation needed other than frame rate as to how that counts for sources that do not have the timecode embedded by the camera itself.
But I will add that having time of day interpreted by creation date and timestamp is handy for editors to have an additional piece of metadata to help them find a piece of media – like when a producer or director goes; “I think we shot something last Tuesday afternoon right after lunch”. That timecode (if interpreted) could be tracked in a separate timecode column for doing those types of searches with a shoot date.
