Good afternoon,

I am using ZK version 9.5.0.3 with JAVA 11. Using the DateBox with the locale of en_GB and a format of DateFormat.SHORT or the official dd/MM/y. According to this website, the date should be displayed as 12/01/2022, however the generated date is 12/01/22.

I created a ZK Fiddle https://zkfiddle.org/sample/oirisd/1-Datebox-en-GB-issue. While testing I also checked and on version 9.6.1 the official format works. Considering that I cannot easily update to zk 9.6.1, what could I do to fix this issue?

Because DateFormat.SHORT change between java 8 and 9, it's better to specify an explicit format : format="dd/MM/yyyy

This format both shows 4 digits of the year in 9.5.0.3 and 9.6.1.

JDK 8 uses JRE as the default locale provider, whereas in JDK 9 onwards CLDR is the default locale provider. (see JEP 252: Use CLDR Locale Data by Default) Because of the change of the default locale provider, the built-in date formats (e.g. DateFormat.SHORT) stand for different formats after JDK 9.

You can use old data format by running JVM with the option:

-Djava.locale.providers=JRE,CLDR
