There seems to be a problem in the way `+` is dispatched for POSIXt/difftime (R 2.8.0 Windows). With the following definitions: t0 <- as.POSIXct('2009-01-01 00:00') halfhour.mins <- as.difftime(30,units='mins') I would have thought that the straightforward answer to Suresh's question would be something like t0 + halfhour.mins * (0:47) And indeed, if we call the class-specific function (which explicitly handles the POSIXt + difftime case), we sensi...

...ay. Additionally, yesterday a big part of ETH had severe network problems during noon time -- hence it wasn't too easy to find out which timeouts where caused by what. I have now re-reverted the mailman settings to what they were before yesterday, and will start tackling the "only" halfhour delays (which I think come from the different qrunner setup that mailman 2.1.x is using -- which is active since about March 4). Thanks for adverting me! BTW: If anyone has time for writing a small perl or python script that automatically retrieves the mailman delay from the two "Received:&q...

Man, R has a steep learning curve (but I suppose you all know this). I have very little programming knowledge, so when I search for answers to my questions, I struggle with making sense of a lot of the pages. I have a spreadsheet that I've read into R using read.csv. I've also attached it. It looks like this (except there are 1600+ entries): > Sunday SunDate SunTime
