Time to remember rising in Dublin and Rome? (6)
I believe the answer is:
easter
'time' is the definition.
The definition and answer can be both related to time as well as being singular nouns.
Maybe there's a link between them I don't understand?
I can't explain the remainder of the clue.
(Other definitions for easter that I've seen before include "festival time" , "A steer (anag.)" , "Egg-rolling time" , "Time to parade" , "Teaser about Christian festival" .)
