[R] Date format

[Yu-Ling Wu]

Hi,

I try to convert a string into date format.
Please see the following two examples. When the 
time is midnight (i.e. 00:00:00), R can't convert 
it correctly and get a value of "NA". How to make 
it work and get the value of "2001-03-23 00:00:00"?
Thanks!!

=Example 1=====================================

> S <- 20010323120000
> sTime <- strptime(paste(S), format="%Y%m%d%H%M%S")
> sTime
[1] "2001-03-23 12:00:00"


=Example 2=====================================

> T <- 20010323000000
> tTime <- strptime(paste(T), format="%Y%m%d%H%M%S")
> tTime
[1] "NA"
