Event Timestamp shows 1970 in Deepstream-Test5-app

When I run the default sample app deepstream-test5-app

The detection results show up on the message broker like this:

How do I ensure that instead of logging the detection event in the epoch time, it shows the time in UTC
@timestamp" : "1970-01-01T00:00:46.399Z

Hi
Refer to this,
5.1 -p 1 (PLAYBACK=1)
(Base UTC timestamp from filename of format - *__M_DD_YYYY_H_MIN_SEC_MSEC_AM/PM_UTC.mp4)
Means - the first video frame timestamp is embedded in the URI.
Example: VideoFileSavedFromCamera__4_11_2018_4_59_59_433_AM_UTC-07_00.mp4
$ ./deepstream-test5-app -c test5_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt -p 1

NOTE: If URI does not have original timestamp embedded, a WARNING will be
thrown to user and current system time will be used as base time for all metadata

5.2 -p 0 (PLAYBACK=0)
(Base UTC timestamp for meta-data from RTCP SR for RTSP Sources
only; any sources other than type=4 will default to PLAYBACK=1)
$ ./deepstream-test5-app -c test5_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt -p 0

NOTE 1: For RTSP Streams, Config file shall use ‘type=4’(NV_DS_SOURCE_RTSP)
in [source] groups

NOTE 2: If the RTSP Camera/Server does not send RTCP Sender Report - or until
the first Sender Report arrive, the buffer/metadata timestamps sent out by
nvmsgbroker will be based on the initial timestamp as zero.
