Time Zone / Daylight Savings Issue in ORC

Summary

Our version of HCM shows UTC time zone, so interviews show the right time in ORC but are an hour later in the candidate confirmation it shows an hour later

In ORC, when we arrange an interview for a candidate the system interview summary shows the time that was booked. When the candidate confirmation email, the time shown is an hour later.

We think this is because our version of HCM is showing GMT and not British Summer Time. 

This means that for 6 months a year candidates will be shown an incorrect interview time. I have enclosed images of the issue.
