[R] Time rather than dates?

Using strptime() and other functions for dates has been very helpful with
the kind of data I often work with. However, I haven't found out how time
as such should be specified. All my attempts result in time *and* date:

>treatment_time<-c("01:02:03","02:03:04") # hours:minutes:seconds
>time.2<-strptime(treatment_time,format="%H:%M:%S")

>time.2
[1] "1900-01-01 01:02:03" "1900-01-01 02:03:04"

Why the 1900-...? I had hoped for some easy conversion from time to
numeric data and possibly back. Assistance would be appreciated.
