Date/Time <---> String

Actually, if I'm reading my calculator correctly, and allowing for it being a signed number, shouldn't that be about 275 billion years in each direction (and I realize I may be unnecessarily splitting hairs)? Anyway, I understood that this was already changed in 8, so that should be better.

And just to restate the point of the thread - we want a vi.lib String to Timestamp function!

They couldn't keep 32bits for the number of seconds because it would not have solved the 2038 limit. Jumping to 64bits was a natural choice, even if it leads to ridiculous ranges (2^-64 hasn't physical meaning either).
Quiz: which day of the week will the LabVIEW timestamp overlap?

You can use the Scan time string function in my Time package. It accepts a format string like at the Format Date/Time function. Also does timezone handling.

Hi all

How can i put the date/time function into this??

[Karissa]

Here is a vi that I use that converts some of my common date strings I get from a database query into a time stamp using the scan from string function.

To put the timestamps into a display like that you will need to change the type from a chart to a graph form.
If the time is not at constant intervals you will need an x-y graph type, see the help for more information on how to bundle time with Y values.
If the time is at constant intervals you can use a waveform graph type instead.

Hi Karissa

Thanks for the example u gave. I was wondering if it is possible for me to use the numeric control to choose my year,month,day and hours instead of wat u sent me??

Hi holla,

where in your code you want to insert this Date Time function? To use controls for the day and time and ... you can create a cluster and transform it to a timestamp.

Hi

When i press stop, it will prompt to save the file for example in notepad. So I want the time to be in the notepad. Leave the numeric buttons first
