you're not guaranteed anything about timeouts. if you are relying on
them for precise timing, you've made a mistake already. within the
context of a GUI, with its (typically slow) human interaction times,
they are entirely accurate enough. for anything else, not at all.
the timeout will execute as part of the glib event loop that its a
part of. your callback could be delayed by arbitrary amounts of time
by other, higher priority callbacks.
however, if the interval is 1 second, then you can be assured that
your callback is almost certainly going to execute very, very close to
once every second.
