Many thanks for your reply, Florian.

I was having an issue (and I thought the problem was in GStreamer),
because gst-launch-1.0 complained about string values being passed
instead of GstDateTime.

With $(date +%Y%m%d-%H%M%S), gst-launch-1.0 complains about GstFlagSet
(instead of GstDateTime).

I have searched how a GstDateTime looks like,  but I cannot find anything.

I’m a coding novice and I’m not sure GstDateTime and GDateTime have the
same structure (which I suspect they don’t).

What am I mising here or doing wrong?

Many thanks for your help,
