Hello how may I help you? What time zone is Ohio located in? Checking that for you. Ohio is in the EST time zone. What about Los Angeles? Los Angeles is in the PST time zone. Okay, can I find out what the times are in both locations if it is 12 AM MST? Checking that for you. Thank you. If it is 12:00 AM in MST, then it will be 11:00AM in Los Angeles and 2:00 AM in Ohio. Very good, thank you for your help today. This certainly makes traveling much easier! You're welcome!
