In the following code snippet,

a <- strptime("121114 0510", "%m%d%y %H%M")
b <- data.frame(date = a, res = 1:5)
class(a)
class(b[1,1])

I am wondering why the class of a and b[1,1] are not the same.
How to make the class of a and b[1,1] to be same?
How about
a <- as.POSIXct(strptime(...))
? (See ?POSIXct)
Thanks a lot.
I have used as.POSIXct(...). I am wondering why the class of a and
b[1,1] are not the same.
Best,
