Problem syncing timezone from Zoho to Macbook Calendar

Problem syncing timezone from Zoho to Macbook Calendar

Hi,

When Zoho Calendar events sync with my ical on Macbook it changes from U.S. Pacific to GMT. My settings on the Macbook are for PST. It works fine with my iPhone calendar, just not the one on the Macbook. I am on OS Sierra.

Can this be fixed?

Take care,
Mark
