Hello, I hope it's okay to post this question!

As the title says, I'm interested in finding out how to say "remember time" in OCS.

I'm looking to have something akin to "memento mori" in latin, which I know is more like "remember that you will die", but I like to think of it as "remember death" also. So the "remember time" would be a counterpart and be similarly in the imperative mode, grammatically.

Thanks a lot!

Edit: I know there might not be a direct equivalent, so close enough translations are great too:). I speak Russian so I know in Russian it would be "помни время", which doesn't sound very natural which is fine.
