...roblem and the use of ntp in such cases. At our department we are running two dovecot servers within an vmware server environment, and unfortunately the timedrift (with ntpd active) exceeds sometimes up to 30 minutes virtual drift within 10 minutes realtime (mostly into future). This is due to some overcorrections within the TSC algorithms of the vmware virtual machine. More information and some hints to workaround are documented here: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1420 Nevertheless we are currently working on evaluating a stable s...

I also read that pairwise.t.test adjusted with the Bonferroni method is not good either because it assumes that the null hypothesis is not rejected, hence overcorrecting TYPE 1 error. It would be great if someone could shed some light on my problem. Thank you in advance! Xiao [[alternative HTML version deleted]]
