Hi Guillaume,

What is your sessionInfo() ?  It works me:

> x <- c("1jan1960", "2jan1960",
"31mar1960", "30jul1960")
> z <- strptime(x, "%d%b%Y")
> z
[1] "1960-01-01" "1960-01-02" "1960-03-31"
"1960-07-30"

> sessionInfo()
R version 2.9.2 RC (2009-08-23 r49375)
i386-pc-mingw32

locale:
LC_COLLATE=English_United States.1252;LC_CTYPE=English_United
States.1252;LC_MONETARY=English_United
States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

HTH,
Jorge
