English to Latin translation

The problem with a phrase like this is that "one damn thing after another"
is a common phrase in English, but not in Latin. But that may be all right
since you seem to be doing this tongue-in-cheek. So here's how I'd do it:

Tempus modo alternum damnatum est.

Tempus -> Time
modo -> just, only
alternum -> one after the other
damnatum -> damned (condemned) thing
est -> is

Now bear in mind that I am not a professional Latin scholar, just a guy
who does this for fun. So before you go getting this engraved or
etched, or even painted, have someone else review it. You might
even consider using a professional translation service.
