Hi,
With GNU make 3.81 the following warnings were seen:
make[5]: Warning: File `.deps/test-xvasprintf.Po' has modification time 4.8e+02
s in the future
make[2]: Warning: File `Makefile' has modification time 1.1e+02 s in the future
make[1]: Warning: File `Makefile' has modification time 95 s in the future
The notation "4.8e+02 s" is a quite obfuscated way to express "4 minutes".
I'm not asking for conversion of the duration to days, hours, minutes, and
seconds. Just using fixed-point notation instead of exponential notation
is enough: "480 s" is understandable. Here's a patch to achieve this
(note that there is no built-in printf directive that would limit the precision
to 2 digits for values between 0 and 10, and drop fractional parts for values
>= 100).

* remake.c (f_mtime): Print time difference values between 100 and
ULONG_MAX in fixed-point notation rather than in exponention notation.
