Money requires care and attention after losing time (6)
I believe the answer is:
rouble
'money' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for rouble that I've seen before include "ready in Belarus" , "Unit of money in Russia" , "Russian coin" , "Russian bread" , "foreign currency" .)
