No, in a timer, you interrupt a totally unrelated thread, so sleeping
would prevent that from running on, as well as preventing other timers
from being run, so it's not an option.

One thing that might work for you would be to re-arm the existing
timer and return from your function, so you get back to it after
a short while.
