Ok short question. I've been using labview for logging data to a text file. I made it comma separated and looks like this:
absolute time, relative time (since start exp), channel 1 data, channel 2 data.
Well, I can sucessfully read from textfile and I'd like the user to be able to view data on a graph.
Problem is, the 2 columns with the time are not correctly changed to numbers, this might have to do with how I saved them:
I used format date/time string to save time, and used ":" between hours and seconds.
So my question: How do I solve this? Can I convert this string to a correct time and date for graphing, or how should I change logging so it
can be converted to a number.

If they are not correctly being converted to numbers/timestamps, please show how you are doing it. Also, it would be nice to see how you are trying to display the data. Is it a normal graph or XY Graph? If it's a normal graph, are you use the offset and multiplier properties to set the x axis?
Just attach an example of the text file and your VI to read it.

I believe it depends on the time format you're using.
This is my example:
