ISOdatetime gives NA for a specific date

Hi all, I am using ISOdatetime, and I just found out that when I do ISOdatetime(1995,03,26,2,10,0) (or any other value under minutes or seconds) I get NA This does not happen with the same time in other dates, nor with different hours in the same date. Any hint why this happens? Using R 2.8.1 under ESS/GnuEmacs under Windows XP Pedro
Daylight savings time, I guess. The clock went directly from 1:59 to 3:00 that day. Other systems behave strangely (er, "handle the anomaly") in different ways:
ISOdatetime(1995,03,26,1,10,0)
[1] "1995-03-26 01:10:00 CET"
ISOdatetime(1995,03,26,2,10,0)
[1] "1995-03-26 01:10:00 CET"
ISOdatetime(1995,03,26,3,10,0)
[1] "1995-03-26 03:10:00 CEST" (SUSE 10.2)
