It can be easily argued that the time on both her clock and Mickey's is a little short of 10:10, especially with the 8 seconds to go on the Mickey countdown to the alarm (presumedly).
8 seconds out of 60 is 0.133333 of a minute (which represents a day). 0.13333x24hours=3.199992hours
That could theoretically shave 3.199992 (3 hours 20 minutes) off of today, if the clock is indicating a date/time, which yields 8:40pm EDT.
