I don't find any way to do that (other than core Xoops preferences which are set correctly) in Xoops 2.0.13.1. Is there a way to completely disable the use of times entirely and ask the posters to simply note the time in the postings on the calendar?

Either that, or set the ALWAYS time of the calendar to a particular zone. (ALL EVENT TIMES ARE IN X TIME XONE) regardless of the system or user settings?

Thank you for your help and for your great work on Xoops and related modules. Your work is quite impressive.
