fastdate of Any RFC3339Micro
this date cartes is very fast(<= 50ns) including * offsetsec() * fromstr("2022-12-13 11:12:14.123456") * now() * utc() * weekday() * tostring()/format!() * eq()/== * add()/sub() * setoffset() * parse("hh:mm:ss.000000,YYYY-MM-DD","11:12:14.123456,2022-12-13") * unixtimestamp() * unixtimestampmillis() * unixtimestampnano() * fromtimestamp() * fromtimestampmillis() * fromtimestamp_nano() * before(&date) -> bool * after(&date1) -> bool * from(v: SystemTime) * from(v: DateTime) * from(arg: Date) * from(arg: Time) * cmp(&self, other: &DateTime)/>/=/<= and more....
