clock

func Now ¶

func Now() time.Time

Now returns the current time. In production this is time.Now; in tests and the LB harness simulator it can be overridden via SetClock.

func SetClock ¶

func SetClock(fn func() time.Time) (restore func())

SetClock installs fn as the time source and returns a restore function that reinstates the previous source. Intended for tests and the LB harness simulator only; callers must defer the returned restore to avoid leaking the fake clock into production paths.

Usage in lbsim:

restore := clock.SetClock(fakeClock.Now)
defer restore()
