@heraclesdev, first of all, pattern is a very misleading name herer. A pettern is what you put as a string into new RegExp(...) Better call it searchstring.
You likely get false because "^" and "$" in the RFC3339 pattern mark beginning and end of the string. I.e. "2019-04-28T06:14:50.142Z" will match but "it is 2019-04-28T06:14:50.142Z" will not.
Hi @jy95 ! Your shortened regex is not correct. It's missing "T" or "t" between date and time representation.
This is the corresponding part of grammar that says it:
date-time = full-date "T" full-time

//// false;//////
It seems it is incorrect.
Could you please explain me....
