Subject: [PATCH] If building (custom) FreeBSD images people tend to patch
 param.h.  In case this happens just before the build is started (within the
 same second) CHECK_TIME actually triggers thinking param.h is in the future
 (see f_Xtime, c_Xtime logi in find(1) sources for the details in !F_EXACTTIME
 case). Using the -mtime -0s (seconds, rather than no unit) avoids this 1s
 race.
