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.

I don't really have time to update this patch to apply against the latest emlxs code so I'm sharing in case someone wants to drive this forward.
