Is it possible to compare timestamps?

[Marcus Mülbüsch]

Hello all,

   I'd like to compare timestamps of two files and have monit alert me 
if one is newer than the other.

   Case in point: Postfix uses some configuration files that have to 
converted into DB-format using the command "postmap 
/etc/postfix/sasl_passwd". If you do forget that, your changes made into 
the text-File have no effect.

   Now I'd like to compare whether the text-file has a newer timestamp 
than the db-file; so I am alerted that I forgot that.

   Is this possible?

Thanks,

Marcus
