Time, part of time jump, in upper left corner. Font? What is this called.

Sorry for the confusing title. I’m trying to figure out what the time in the upper left hand corner when you enter in a time to jump to is called. Also, where might I change this? I’m trying to get this set up for my mom and she loves everything about it but her eyesight isn’t great and she can barely read it.

Here is a screenshot as I’m probably not explaining it well. I’m really just trying to get that bar bigger with a larger font.

Thanks for the help
