Here is some crosschecks:

Dear R list,
I noticed the following 'problem' when changing the format of dates
created with seq.dates() (from the Chron library) using as.POSIXct()
(R 1.8.0 on OSX 10.2.8):
datesTest<-seq.dates(from="10/01/1952", length=3, by="days");
datesTest
[1] 10/01/52 10/02/52 10/03/52
# Now changing
