Status Update - am I sleep-posting?

[MossCommuter]

At 01h17 today my status was updated (to the same text as an update I made some time ago).

At that time I was asleep!

How was my status set? I am certain I did not do it.

Oh, hang on... 01h17 yesterday was Saturday morning

It's entirely possible I posted that (even thought I don't remember)
