If the system time changes during the execution of fastboot we might see some strange output such as: Sending sparse 'super' 4/20 (254972 KB) OKAY [-516.263s] Fix it by changing now() to use clock_gettime(CLOCK_MONOTONIC). I confirmed that all callers of now() are using it for relative time and not time since the epoch. Change-Id: Ic3e9442c2ab21dfb076bfed88915085a183754b0
