squidalyser 0.2.55对时间戳处理的bug

mysql5、4 和mysql3对时间戳的处理方式问题，前期用squidalyser.pl将squid日志导入到mysql 3中，对于时间戳字段的处理都没有问题，现在mysql server 3升级到5后，发现mysql 5、4对时间戳的处理方式和mysql 3很不同，导入的时间戳都变成了1970-01-01，squidalyser.pl认为导入的数据都是过期数据，导入完成就全部删除了，导致无法分析和查看代理服务器上网日志，在squid官方网站也有人提出此问题，但是也没有解决办法，该如何解决这个问题，请大家帮忙解决相关问题；

以下是导入数据的脚本和删除过期数据的脚本squidalyser.pl，这个程序目前原作者已经停止更新；
