When the timer for the quantum interface bomb starts, it is displayed as '0:60". Sixty seconds is of course one minute, so it should have read "1:00" then "0:59". Unless the number of seconds in a minute has changed in the future.
Response: There's nothing wrong with a timer displaying 0:60. I can type in 0:90 on my microwave and it will run for 90 seconds, or I can type 1:30 and it will run for 90 seconds.
