I ran into a issue where the time on incoming IM messages were off. The phones were showing the correct time, the timestamp on phone calls were correct, the PC was showing the correct time and the time on the server was correct. When you receive IM messages the time stamp for those messages come from the ShoreTel Service Appliance and the Service Appliance gets the IP for the time server from the ShoreWare Director Site settings for the site it belongs to. On working on this issue I found that you can manually update the time server. It is a pretty easy process, you will need to SSH into the Service Appliance and use the command "ntpdate -u <IP OF TIM SERVER>" Below is a copy of the output from when I ran it and the commands and important info has be bolded and underlined. To look at the time you will need to enter the svccli shell and enter the getstatus command. Once you have updated the time, you will probably want to reboot the Service Appliance to make sure that the time sticks after the reboot.
