you take a look at this?

Hi all,
Please, how could I calculate the time that two time segments has in common?
Is there any function to perform this calculation?
For instance, given four POSIXlt objects...
endPeriod<-as.POSIXlt("2008-09-30")
startPeriod<-as.POSIXlt("2007-10-01")
endProject<-as.POSIXlt("2007-05-31")
startProject<-as.POSIXlt("2006-12-01")
that limit two time segments...
project <- as.numeric(endProject-startProject)
period <- as.numeric(endPeriod-startPeriod)
How could I calculate the time project and period overlap?
Thanks for your help!
Ricardo
