10:00 pm MST is not suitable to schedule meetings
When planning a call between Mountain Standard Time and Central Time, you need to consider time difference between these time zones. MST is 2 hours behind of CT.
It is currently 10:00 pm in MST, which is not a suitable time to arrange a call or meeting with someone in CT, since it is 12:00 am there, which not within the optimal time span between 7:00 am and 11:00 pm.
You could, however, schedule a call between 5:00 am and 9:00 pm your time. This time span will be between 7:00 am and 11:00 pm in CT.
