Are the two records on the same IOC?  If yes, then perhaps a subroutine record on the same IOC with inpa and inpb being links to your two records would work?  The subroutine would look something like:

include "dbAccess.h"

epicsTimeStamp timea, timeb;

dbGetTimeStamp(&psub->inpa,  &timea);
dbGetTimeStatmp(&psub->inpb, &timeb);
psub->c = epicsTimeDiffInSeconds(&timea,&timeb);
