Request to update America/Mexico_City Timezone info

[rloview]

Describe the bug
I use version 1.0.7 or 3.2.12
I think that need to update the timezone info of America/Mexico_City.
The America/Mexico_City time zone no longer applies DST.
However, if I create a DtStart object with the Mexico_City timezone, the time sets with DST applied.

To Reproduce

import net.fortuna.ical4j.model.DateTime;
import net.fortuna.ical4j.model.TimeZone;
import net.fortuna.ical4j.model.TimeZoneRegistry;
import net.fortuna.ical4j.model.TimeZoneRegistryFactory;
import net.fortuna.ical4j.model.property.DtStart;

public class Test {
	public static void main(String[] args) throws Exception {
		long current = System.currentTimeMillis();
		
		DtStart dtStart = new DtStart(new DateTime(current));
		TimeZoneRegistry registry = TimeZoneRegistryFactory.getInstance().createRegistry();
		TimeZone dtStartTimezone = registry.getTimeZone("America/Mexico_City");
		dtStart.setTimeZone(dtStartTimezone);
		System.out.println("America/Mexico_City DtStart " + dtStart.toString());
	}
}

Expected behavior
The output information should be DTSTART;TZID=America/Mexico_City:20230804T043327 same as GMT-6.
However, the result of executing that code is DTSTART;TZID=America/Mexico_City:20230804T053327

@benfortuna Hello. Could I know the schedule that the timezone information will be updated to 2023c version?
For example, I checked in the file below that the latest version is using 2022g.
https://github.com/ical4j/ical4j/blob/ical4j-3.2.12/src/main/resources/zoneinfo-global/America/Mexico_City.ics

I'm sorry to interrupt but please reply.

Hi, ical4j has the option of updating itself at runtime with the latest timezone definitions from tzurl.org. So whilst the definitions in git may be a bit out of date, it is best to check the tzurl.org site to see if that definition is correct.

We also maintain that site, so if you find that definition is incorrect let me know: https://www.tzurl.org/zoneinfo/America/Mexico_City
