Today I had a support call from a dba complaining about
solaris 'find . -mtime +1 ' not reporting files older than 24 hours.
To my surprise (I've been using unix for 20+ years now), the -mtime argument
has to be interpreted as whole days. It makes sense, and it actually
make find . -mtime 1 a useful thing to ask.
However, I did check documentation and the POSIX spec, and looked for
different implementations, in my case gnu/linux find and UWIN (ast).
Gnu find conformed to the posix spec (rounding down to whole days),
but UWIN gave me what our dba expected, files older than 24h.
I also tested the daystart option, which did not show *any* files.
( I had three, one each for noon 10/1, 10/2 and 10/3 )
$ find . -daystart -mtime +1
$ find . -mtime +1
./m10011200
./m10021200
but this looks like a conflict with the POSIX spec, not ?
Cheers,
Henk
