Second time this is happened.
First time when using iOS 11.0.2, and now with iOS 11.2.6. iPhone 7.
First time, I had to reboot the phone to get the clock back.
This time, the clock came back after I locked the phone and unlocked again.
Anyone else experienced this? Is it a known issue?

I had this same issue from iOS 11.0.0 to 11.2, than I found that cause is widget of czech T-mobile app. It happened every day. (And I had to restart phone every time) It was terrible...
