How do time zone differences affect freelancer-client relationships globally?

One of the issues to watch out for in freelancing is the issue of time difference, especially when you are working for international clients. You needs to make sure that you are putting in your best to make sure that you explain to your clients how time difference of your country can affect the delivery of your tasks. This will make them to understand if anything happens, or there is a change in the delivery time. Have you found yourself in this situation before?
