Time Warp or Matrix Error?

Something really, really strange happened last night. Left the bed @ 03:00 a.m. to take a piss and checked the alarm clock when I came back - 03:01 a.m. on the display. Then I turned round, trying to sleep. I couldn't, so I checked the clocks display again after approx. 5 minutes. And - quelle surprise! - the displayed time was 02:53 a.m. . I felt quite puzzled about the time moving backwards and I don't have any proper explanation for this apart from a broken clock, which, after this incident, seems to work nicely again. Could anybody please come up with a proper, logical suggestion how this could happen. And no - I wasn't drunk, suffering from fever or on drugs.
