Subject: Date & time validation

Hi all,

I am looking for an easy way to validate date and time values in a
script I have written.

The script takes values from a large file containing various data sets,
some dates and some times. I need to validate these dates and time
values once I have loaded them into a variable and I was thinking of
doing this through an a date check and time check object for example:

date1 = field[2]
date1 = dateCheck(date1) if date1 != ""

date2 = field[23]
date2 = dateCheck(date2) if date2 != ""

time = field[24]
time = timeCheck(time) if time != ""

def dateCheck(dateData)
  I need some code to check what ever is in this string and check for a
valid    date of yyyy/mm/dd. The data being checked can be anything, so
I need to know does it match the date format of yyyy/mm/dd, if so return
true otherwise return an empty string
end


def timeCheck(timeData)
  similar idea with the time I need to check the data is hh:mm:ss
otherwise return an empty string.
end


Any ideas on how to do this? I was looking a the docs for date and I am
struggling to make head way at this stage.

Thanks in advance!
