系统时间也引发软件安装出错

今天在freeBSD下安装软件时, 报了一个错:
# make install
===> Vulnerability check disabled, database not found
===> Extracting for libtool-1.5.26
=> MD5 Checksum OK for libtool-1.5.26.tar.gz.
=> SHA256 Checksum OK for libtool-1.5.26.tar.gz.
===> Patching for libtool-1.5.26
===> Applying FreeBSD patches for libtool-1.5.26
===> Configuring for libtool-1.5.26
checking for a BSD-compatible install... /usr/bin/install -c -o root -g wheel
checking whether build environment is sane... configure: error: newly created file is older than distributed files!
Check your system clock
===> Script "configure" failed unexpectedly.
Please report the problem to ade@FreeBSD.org [maintainer] and attach the
"/usr/ports/devel/libtool15/work/libtool-1.5.26/config.log" including the
output of the failure of your make command. Also, it might be a good idea to
provide an overview of all packages installed on your system (e.g. an `ls
/var/db/pkg`).
*** Error code 1

Stop in /usr/ports/devel/libtool15.


主要的ERROR信息为:
error: newly created file is older than distributed files!
Check your system clock

调整时间:
ntpdate 202.130.120.114

结果就OK了.


freeBSD在安装软件时还测试文件的create time的?
