Description

ddi_get_time() returns a Unix timestamp based on the current TOD. If the TOD setting changes for whatever reason (daylight saving time adjustments, NTP), the value returned by ddi_get_time() may change non-monotonically. This makes it unsuitable for calculating timeouts and wait times.
