I quickly went through LPL's videos and didn't see many videos about time locks, except for "[876] Electronic Ballot Box Time Lock Defeated" which was trivially defeated with a manual reset switch under a sticker. I'd presume that a time lock with no password bypass (like a bank) could be more secure than a standard combination lock, however, you'd be trading in a lot of accessibility for security; you wouldn't be able to access it even if it was an emergency.

You could have a time lock which just opens for a few hours everyday while you are present; the schedule of which can only be changed one week in advance (if that's possible.)
