FoxClocks shows times around the world at the bottom of your browser. It deals with daylight saving time so you don't have to.
It's really good but what about adding date?
After spending some time playing with this extension, you can make it work by: pin extension (easy access), then click on options, on the new tab with adjustable timer of extension, do your web serving and the time will stay on the page only. If you have some other tabs open, can just copy & paste the time adjustable tab and then click back button on browser to have timer on the tab you wanted in. Will not work well with row extention on YT.
Love the extension but it has stopped working, it is not loading anymore, I have to click on it multiple times in order for it to show up but even then, it will close on me again. Some recent update broke this one, it was working flawlessly.
