From: Yusuke Okada <okada.yusuke@jp.fujitsu.com>
The "%f" specifier in g_date_time_format() is only available in glib
2.65.2 or later. If combined with older glib, the function returns null
and the timestamp displayed as "(null)".
For backward compatibility, g_date_time_get_microsecond should be used
to retrieve subsecond.
In this patch the g_date_time_format() leaves subsecond field as "%06d"
and let next snprintf to format with g_date_time_get_microsecond.
