Thank you for your quick and clear answer.
Yes, your suggestion is what I initially tried but ran into multiple road blocks such as there is no 'delete' function active when attempting to delete the clock format code lines in jmw-tray and there is no /usr/local/jwm_config/tray listed in the system. I wish I had the tray configuration that you show in your screenshot, but, it's appears nowhere in this system.
So, I did a 'restore master backup' this way: JWMDesk/Profile/back up profiles/jwmrc-personal/restore. This cleared the tray of my personal apps including the offending PupClockset coding. Then I reinstated personal apps through the jmwdesk/launcher tab per usual procedure. Hopes this helps someone else with a similar glitch.
