How to compare different timestamps and check which one is greater.

[OmarTariq]

Hi Guys,

I have a small question regarding datetime.

I have the following data in an array in timestamp format .

01:00:00.000
19-05-2009


01:00:00.000
22-05-2009


01:00:00.000
23-05-2009

What I want to do is to check which date is greater then the other.  Simply my question is how to do comparison between dates , specially when they are in time stamp format

Secondly I would like to ask if I have a timestamp which has the following values

01:00:00.000
22-05-2009

How do i convert it into seconds ?

Thankyou

Just use a comparison function directly. The functions are polymorphic. If you don't understand what polymorphism is, then please review the LabVIEW Help and the LabVIEW tutorials, as they cover this behavior.

Just use the Numeric Conversion functions. This will give you the number of seconds number of seconds that have elapsed since 12:00 a.m., Friday, January 1, 1904, Universal Time.

You can build an array of time stamps and use the array min/max to compare sets of timestamps.

Use the to double conversion to get seconds since...

Oops, missed that we're dealing with more than 2. Yeah, if you've got more than 2 then an array is the way to go.
