how to get the time from a file recorded?

[GerdW]

Hi EduU,

correct!

[EduU]

Well GerdW,

I put the right time in the header 

but now I need to read this time, how I can read the time and put it in seconds??

Thanks for the help 

[EduU]

Well GerdW, I made an example to maybe you can understand better

I make that code:

And the result in Front panel is that:

Now I need take that time "14:46:01" and make it a number, How I can make it?

And the Identification, can be a lot of characters... 

I tryed String subset but I don't work, if you can attch an image with the solution

I will be pleasure!

Thanks 😃

Hi EduU,

you will find a lot of threads on time string to timestamp conversion in this forum...

Hey GerdW, I tryed what you said but it wont work =x

In my string I have a text too, I made an example here I will attach an image to you take a look

Maybe I'm doing something wrong =x

My output is showing only 0.

Because I have to use it at the concatenated string not only in data and time.

and after I have this output working, I need to take only the time and transform to a number of seconds... I know I can make it with unbundle cluster, but when I'm trying appears that I connect a time stamp to a cluster with 0 elements. How can I do it?

Thanks mate

Hi EduU,

when there is other text before your timestring you have to cut that first - how should ScanFromString know about that? SFS searches for a timestamp and only finds some "garbage" text...

You can

- use another scan format string (i.e. put another "%s " in front of your scan format string)

- strip the additional string before the ScanFromString function

Well, could you attach a image for me with a simple example?

I think I didn't understand =x

[GerdW]

Hi EduU,

try a format string of "%s %<%d-%m-%Y - %H:%M:%S>T"...

[EduU]

GerdW,

appears (too many format specifiers) I have to make one to one

I did something here and it works I will attach the image...

but I made it at labview 8.6

in labview 7.1 ( my program is in that version) I can't scan relative time... so didn't work...

I tryed extract the 3 numbers separated, but I don't know how to eliminated the ":"

works in labview 8.6:

But in labview 7.1 I don't have this "%t" at scan string... so I tryed a different way:

In output1 I get the hour, but when I try to get the minutes.... it don't appear because I have a ":" before the number... I have tryed the %s to took off the ":" but when I use %s the hole string dessapear. So I need a way to take off this ":"

Could you help me on that??

Well I understand now what you said.. I can extend the scan string to more than one variable... but I tryed what you said... and Time Stamp still don't work... but I need it to LabVIEW 7.1 so please help me with that =D
