void clock_adjust_ticks

(

clock_time_t

howmany

)

Adjust the system current clock time.

Parameters

dt	How many ticks to add

Typically used to add ticks after an MCU sleep clock_seconds will increment if necessary to reflect the tick addition. Leap ticks or seconds can (rarely) be introduced if the ISR is not blocked.
