>That won't work because at 16:50, if you use the above command, the next update will occur at 16:05. I think the solution would be a bit more complex than that.

Absolutely correct. I was just showing how to do math using the time. I'm not sure exactly what the final outcome should be, he may only want a 12 hour clock, he may want am or pm. But the fact that there is a way to perform a math function on the time is the answer.

For one of my applications I actually use two or three lines of code using iif() for am or pm, and turning the 24 hour time into 12.

I thank you for pointing out the issue and possible this conversion will aid the original questioner to the correct path.
