Normally a difference of seconds, minutes or even hours should be negligable when you want to delete messages older than 5 days for example. Do you need to be exact or do you want to prevent accidents from a faulty HW-clock on the client (usually an imap-server should use ntp already and have the exact time) ? In the second case something like Net::NTP might help
