Then that would be less than 24 hours for 1023.

1.4 minutes X 1023 = 1432.2 minutes
1432.2 minutes / 60 (min/hr) = 23.87 hours

Cano is correct, giving him some room to round off. 1.4076246334310850439882697947214 minutes per cache will get you a little more accuracy.

I figured it in seconds. There are 3600 seconds in and hour, so 3600 X 24 hours = 86400 seconds. 86400 seconds / 1023 caches = 84.5 seconds per cache, which is just over a minute.
