Silence some Coverity warnings and improve code consistency.
Coverity complained about possible overflow in expressions likeintresult = tm->tm_sec * 1000000 + fsec;on the grounds that the multiplication would happen in 32-bitarithmetic before widening to the int64 result. I think theseare all false positives because of the limited possible range oftm_sec; but nonetheless it seems silly to spell it like that whennearby lines have the identical computation written with a 64-bitconstant.... or more accurately, with an LL constant, which is not projectstyle. Make all of these use INT64CONST(), as we do elsewhere.This is all new code froma2da77c, so no need for back-patch.
