Re: Converting a given double to a date

[Tony Plate <tplate@blackmesacapital.com>]

Something like one of the following should do the trick.

> x <- c(20010223, 20040530)
> timeDate(as.character(x), in.format="%4Y%2m%2d")
[1] 2001/02/23 2004/05/30
> timeCalendar(y=floor(x/10000), m=floor((x %% 10000) / 100), d=x %%
100)
[1] 2001/02/23 2004/05/30

A gotcha here is time zones.  If you are using something other
than:

> options("time.zone")
$time.zone:
[1] "GMT"

then you need to be careful with time zones -- the dates might not be
getting the time of day that you want.
