Its a very valuable domain. You could probably sell it for at least a few hundred grand+
With a working, operating site that has content and engages visitors, adds value to the web and maybe even has good social profiles (no fake followers etc and engagement) that could possibly add double the value to the already valuable domain.
You have some good options and I would consider visiting a dedicated domain name forum to see what primary people into domains suggest too.
I like what you have on it now, but just putting some adsense on wont make you buckets of cash.
Also in terms of search volume, there are 300k searches in Google UK a month for the term "time". Based on the amount of traffic you are getting, you are getting minimum and that could be improved massively- quite easily with a developed site. Plus, thats not factoring other country search traffic like the US etc.
All the best and please keep us updated!
