How do I change the current time?
You can change it in your User CP. To change the default time for guests/new members you need to change:
ACP > Configuration > Date and Time Formats > Default Timezone Offset
I tried to change the time in ACP>Configuration>Date and Time Formats> to the GMT -5 hours and it always bounces back to the default GMT time ??
Did you change it in your User CP too?
