## When a ``zeek_init`` handler executes, Zeek has not yet seen any input
## packets and therefore :zeek:id:`network_time` is not initialized yet. An
## artifact of that is that any timer installed in a ``zeek_init`` handler
## will fire immediately with the first packet. The standard way to work
## around that is to ignore the first time the timer fires and immediately
## reschedule.
