Japan Standard Time shows up as "JDT" when it should be "JST"

Hello,

Japan time shows up as JDT when it should be JST (no daylight savings or summer time shifts in Japan).

Steps to reproduce:

1. Install and set up Clocker 23.01 (109)
2. Open the clock from the menubar
3. Click the + button
4. Add Asia/Tokyo then give it the label "Japan" save the entry
5. Mouse over the entry for "Japan"

Results: We see JDT (UTC+9.0) -- The UTC time offset is correct, but the label should not be JDT. It should be JST.

Thank you!
