Do you ever read the documentation ?

You might then have read why the above will never work.

You probably need this:

https://www.freepascal.org/docs-html/current/rtl/dateutils/iso8601todate.html

or even this

https://www.freepascal.org/docs-html/current/rtl/dateutils/scandatetime.html

If you need full timezone handling, then there are no such routines in the
RTL. However, there is somewhere a package (I believe it is mentioned in the
wiki) that handles timezones and whatnot.
