Why is it optional? More complete answer. Rules used to fill the is_adjusted flag: - System clock: is_adjusted=1 because the clock can be set manually by the system administrator, except on Windows: is_adjusted is 0 if GetSystemTimeAdjustment() returns isTimeAdjustmentDisabled=1 - Process time: is_adjusted=0 because I don't know an OS where the process time can be modified - Monotonic clocks: is_adjusted=0 on Windows, Mac OS X and Solaris, is_adjusted=1 on Linux, it is not set otherwise. We may also set is_adjusted to 0 on other OSes and so the key would not be optional anymore. Said differently, is_adjusted is only 1 for system clocks and for the monotonic clock on Linux.
