I could not fix a time with any tutor for the last couple of days as when pressed it says “No more time available. Try another day or later”. hence, request you to find a solution asap.
For the time being, set your time zone to UTC (GMT+0) in Settings and make sure that you calculate the right time with your tutor’s time. There’s another thread about “No more times available. Try another day or tutor” in the Support Forum.
Mark suggests using this time zone converter to get it right:
I was able to sign up for a conversation in this way and then switched back to my original settings. I also notified the tutor of the conversation time on his wall.
