This should probably not be mixed into the flags options list.

It seems odd to have the user provide a double here instead of a ISO 8601 datetime, which is what the spec requires / ends up in the playlist.
If you do not want to handle the datetime string parsing, at least it would be good to give a hint what exactly the double value is expected to be here.

However usability-wise I would prefer to accept a proper date/time here…

Is there an example of how to accept a string as the option and then do the
parsing that I could base the code on?

For the option itself, just change the type (of course adjust the struct variable as well):

{"init_program_date_time", "Time to start program date time at",
 OFFSET(init_program_date_time), AV_OPT_TYPE_STRING, .flags = E},

And for parsing maybe have a look at libavformat/dashdec.c around line 191 which does
rudimentary ISO-8601 parsing.
