Time flies — in small amounts (6)
I believe the answer is:
traces
This clue might be a double definition.
'time flies' is the first definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'small amounts' is the second definition.
(I've seen this in another clue)
'in' is the link.
Can you help me to learn more?
(Other definitions for traces that I've seen before include "Vestiges (that may be kicked over?)" , "Follows or discovers by examining evidence" , "Signs in crates" , "Finds; small quantities" , "Finds; hints" .)
