Players can change their time format but I want them all to have the same time format. I did configure the clock panel to have the time format "h:mm tt" but players always get the default "HH:mm". Is time format client side or something?

how do players change the time format ? If you have your settings set in the config ?
"Margin": "0 0 0 0.01",
"Order": 1,
"PanelSettings": {
"ClockUpdateFrequency (seconds)": 4,
"TimeFormat": "HH:mm"

Yes, thats what i said, I did configure the clock panel to have the time format "h:mm tt" but it doesnt seem to have any effect. Players always get the default "HH:mm" unless they manually change their time format.
