times Dont Sync properly

times Dont Sync properly

Hello. 

I have a Zoho Mail Standard account and have installed the Zoho mail app for my BlackBerry. When entering appointments in my calendar for certain times, I've noticed they change on the Zoho calendar website once everything syncs. Appointments entered from say 0830-1800 show up as 0130-1030. 

How to I set this up so the times are correct between the phone app and the calendar website?
