[R] time zones and the chron to POSIXct conversion

[Jannis]

Hey R folks,


i found some strange (to me) behaviour with chron to POSIXct conversion. 
The two lines of code result in two different results, on ewith the 
correct time zone, one without:

library(chron)
as.POSIXct(chron('12/12/2000'), tz = 'UTC')
as.POSIXlt(chron('12/12/2000'), tz = 'UTC')

Only the code below would give me a POSIXct object with the correct time 
zone:

as.POSIXct(as.POSIXlt(chron('12/12/2000'), tz = 'UTC'))


Is this a bug or desired behaviour?



Thanks a lot
Jannis
