Subject: [PATCH] timers: update loop time before main module

We use the loop time for timers to avoid extra syscalls, but because
there's a non-trivial amount of startup time the loop time is stale and
a timer created on the first turn of the loop will fire "early"
explicitly update the loop time before executing the user's javascript
