java - Android: time intervals with deep sleep (System.nanoTime(), System.currentTimeMillis(), SystemClock.elapsedRealtimeNanos()) -

i implementing application has minimum api level 14 (this important) , requires consistent interval measuring. no need ms precision, needs counting time (elapsed seconds). far, treat time intervals, knew these solutions:

system.nanotime() - works great if android running, stops on deep sleep (this bad). system.currenttimemillis() - good, not appropriate because can changed user or code setcurrenttimemillis(long). systemclock.elapsedrealtimenanos() - counts elapsed time on deep sleep, requires api level 17.

is there way reasonable second-precision interval measuring on api 14? i thought using system.currenttimemillis() listening broadcast intents see if scheme clock has changed. not seem best solution.

have tried systemclock.elapsedrealtime() ?
