DESCRIPTION

ddi_get_time() returns the current time in seconds since 00:00:00 UTC,

changing. In other words, the value is not monotonically increasing and
therefore it must not be used to set wait or expiration intervals. For
that, instead use ddi_get_lbolt(9F) or gethrtime(9F).

RETURN VALUES

ddi_get_time() returns the time in seconds.

CONTEXT

This routine can be called from any context.
