Yes or hitting the menu button or toggling the screen. I was checking to see how the dark/light invert at noon worked and was confused when the colors changed but the clock did not. Waited for a few minutes and nothing changed so I hit the menu and noticed it jumped into the correct time when I minimized it.
I toggled some settings to turn off the dynamic light/dark to see if that was it but I couldn't get it to change.
If it makes a difference I don't use the system wide ntp time sync and I use the manual setting.
