I don't think you need to change the Asterisk source for this (particularly
since it is supposed to be wiping the answer time there).

If you want to keep the original answer time, use a custom field in your
CDR, and set it prior to resetting:

exten => Set(CDR(orig_answer)=${CDR(answer)})
exten => ResetCDR(v)

Note the usage of 'v' to keep the custom variable that you just set.
