Present times as a result of this (6)
I believe the answer is:
hereby
'as a result of this' is the definition.
(I've seen this in another clue)
'present times' is the wordplay.
'present' becomes 'here' (both can mean in attendance).
'times' becomes 'by' (both can mean 'multiplied by').
'here'+'by'='HEREBY'
(Other definitions for hereby that I've seen before include "Not far off" , "(Formally) with this" , "By this means or act" , "By this means, as result of this" , "By means of this, legally speaking" .)
