This was reported a few days ago for hobbitlaunch on the Hobbit server,
but yes - the same issue occurs on clients.

What happens is basically that hobbitlaunch remembers when it last
ran one of the tasks, and then it will run it again when the time
becomes (last_time_it_ran + interval). So if you set the current time
back, it will stop running for some time.

Clocks just aren't supposed to jump backwards ... 

There are a couple of ways to fix this. One is in the current snapshot,
but I might do it differently.
