Clock VI with elapsed time

[inuyasha84]

Hi guys. I want to realize a clock that show me hours and minutes. I was using the elapsed time.

Could you check if this solution is fine?Because I'm not so sure if I have done mistakes.

The first issue I see right off the top is your elapsed time in seconds is never going to equal 60, at least not every minute like you expect it to occur.

[apok · Accepted solution]

you can always use "tic count"

Personally, I'd convert the elapsed seconds to a timestamp and play around with the timestamp display to be "HH:MM:SS".

Hi cross what are those timestamps you are talking about?can you do an example?I'm curious to learn this feature.

Thank you

A timestamp is an internal LabVIEW data type.  You can find controls in the Numeric palette.  It's use is very common in both VIs and LabVIEW primitives.  For example, on the Timing palette, many of the VIs use it for inputs and outputs.  The Waveform Data Type (WDT) used by most NI data acquisition APIs, contains a timestamp.

Timestamps come in two flavors - relative and absolute.  Absolute timestamps contain the number of seconds since midnight, January 1, 1904.  Relative timestamps shift this epoch to something more convenient for the particular use case.  For example, the NI-SCOPE driver returns WDTs whose timestamp is the time of the first data point relative to the trigger position in the waveform.  Under the hood, timestamps are a 128 bit fixed point number with enough range and resolution for all but the most demanding situations.

Check out the LabVIEW help for more information.

something like this...

Why convert to a time stamp?  You can drop a numeric indicator, go into the display format properties, and set it for relative time.

also, you are right....
