JavaCard OS

In my application, I need to store Date/Time info in java card. I know JavaCard 3.0 support Class Date, but the platform I am using is JC 2.2.2
Is there any similar class that can be used in JC2.2.2? Is it possible to store date info in JC2.2.2?

You can store date/time information as unixtimestamp, when you use it, you can convert it to hommization string.
