Subject: time-util: introduce deserialize_timestamp_value()
X-Git-Tag: v231~623^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ebf30a086dfa526ca048cf14ae16bb403f3dcd12;p=platform%2Fupstream%2Fsystemd.git

time-util: introduce deserialize_timestamp_value()

The time-util.c provides dual_timestamp_deserialize() function to
convert value to usec_t and set it as value of ts->monotonic and
ts->realtime.

There are some places in code which do the same but only for one
clockid_t (realtime or monotonic), when dual_timestamp_deserialize()
sets value of both.

This patch introduces the deserialize_timestamp_value() which converts
 a given value to usec_t and write it to a given timestamp.
