Subject: Checking datetime value

Hi,
You can check the dataset for any patterns that are unique for the datetime values.
For example:
vec1 <-? c(as.character(Sys.time()), format(Sys.time(), "%a %b %d %X %Y %Z"),4324343,format(Sys.time(),"%m-%d-%Y %H:%M:%S"),"aZZCRDDS")
?vec1[grepl(":",vec1)]
#[1] "2013-11-07 15:04:27"???????????? "Thu Nov 07 03:04:27 PM 2013 EST"
#[3] "11-07-2013 15:04:27"???
A.K.

Hi ,
I would like to check if a column contains datetime values. (column may
contain any datetime format or just numbers or string). Request your help
