TimeStamp Updated when Daily Quota Reached

[SidGauVic]

I've got the script running and it added the videos from the last day. When trying to add videos from a week ago, I got the following error:

Jan 4, 2020, 9:00:31 PM Error Error: 90 videos were not added to playlist correctly, please check Debug sheet. Timestamp has not been updated.
at updatePlaylists(Code:151)
at insideUpdate(Code:427)

Upon checking the debug sheet, I saw that I was hitting the Youtube API quota limit. I tried running Update Playlists again, but this time the the script logged that I've hit the Daily Quota Limit, however, it still updated the TimeStamp.

I'm thinking that any quota related error should mean the time stamp is not updated.
