I have been scheduling posts using Zoho Social for a specific time (6pm). However the posts are not being posted to Facebook or Instagram until an hour past the designated time (7pm). 

When I look back into Zoho Social it shows it was posted at 6pm however in Facebook and Instagram it shows it was posted at 7pm. 

I have double checked the settings of the user that scheduled to post in One.zoho.com and they are the correct settings (MDT).

How do I solve this problem so the posts are actually being posted at the intended time?
