+Subject: [PATCH] gst-record: switch to gettime function to CLOCK_MONOTONIC
+
+When system time is changed (e.g. from NTP) and buffer duration
+is bigger, the gst-record stops. It should use the CLOCK_MONOTONIC time.
+
+This patch is updated from
+https://gerrit.automotivelinux.org/gerrit/#/c/9417/
