Cache TimeZone Abbreviation (i.e. EST, PST, etc...)

Dear Fellow Cache Gurus:   I would like to know if there is either any built-in Cache Date/Time function or an easy way to include a timezone abbreviation such as EST, PST, MST, etc... within the Cache Date/Time formats.

I read through the Cache Documentation but could not find anything to achieve this.

So if I do the following command:   $ZDateTime($H,1,4,,,4,,,,,"InvalidDate"), then I get an output like this:   02/27/2025 11:10AM

But I am looking for the output to be formatted like this:    02/27/2025 11:10AM EST

Any feedback, suggestions, etc.... would be greatly appreciated.   I am sure some of you have stumbled across this type of dilemma over the years, so hopefully there is a simple answer.

Best Regards and Go Team!!!
