I'm sure there must be a better way to do this. But I couldn't find it in the documentation.

I think I'm supposed to use MonoTime here, right?

It's trying to look up the local timezone at compile time.

You need to specify a time zone:

    static time =
        SysTime(DateTime.fromISOString("20220101T000000"), UTC()).toUnixTime;
