How to parse datetime with milliseconds and timezone?

[StasLina]

I'm trying to convert the date and time with the time zone and milliseconds, but it doesn't work. How can this be done correctly? Without milliseconds it works, but me need milliseconds too.

    std::istringstream in{ "2024-04-30T10:31:38.326+03:00" };
    sys_seconds tp;
    in >> date::parse("%FT%T%Ez", tp);

Change:

sys_seconds tp;

to:

sys_time<milliseconds> tp;

(adding namespace qualifiers if necessary)
