Clock riddle

• In this riddle we will use as many clocks as the digits of the password. Imagine we have a password 4-7-2 to unlock the lock. For this example, we will need three clocks:

• One that’s says 4 o’clock
• One that’s says 7 o’clock
• One that’s says 2 o’clock

It could be displayed as time of different regions on earth with different time zones. For example, Athens (4 o’clock), Dhaka (7 o’clock) and London (2 o’clock)

Another example would be to have two clocks for a six-digits code (e.x. 2:32 and 3:45)
