Detailed Description

Useful to write and reproduce tests that depend on specific time factors. This API allows to fake the timeval provided by gettimeofday() by using a small shim osmo_gettimeofday().
If the clock override is disabled (default) for a given clock, osmo_gettimeofday() will do the same as regular gettimeofday().
If you want osmo_gettimeofday() to provide a specific time, you must enable time override by setting the global variable osmo_gettimeofday_override (osmo_gettimeofday_override = true), then set the global struct timeval osmo_gettimeofday_override_time wih the desired value. Next time osmo_gettimeofday() is called, it will return the values previously set.
A helper osmo_gettimeofday_override_add() is provided to easily increment osmo_gettimeofday_override_time with a specific amount of time.
