Adding time stamp to table/array

Question

Hi,
In my posted VI I am displaying some collected temperature data on a table.  What I am having trouble with is getting the time data to work properly on the table.  When I set the include time data to true, it reads out the time as 1904 etc. I'm not sure if it's possible for me to include a time stamp in my array because when I try to convert a time stamp to a double precision float, the output is still a cluster, and thus cannot be added to the array.  I've also tried to convert the array to a string and concatenate the time stamp on, but the signals input for the table does not accept strings, and because I would eventually like to export this table to a spreadsheet in a file, I don't really want to link the strings to the indicator directly.  I've tried to work with the instrument as well, but when I read time data from it it gives it back in the form of multiple numbers, such as 2008, 8, 28, 13, 30, 31.12 and I can't consolidate it to one number.  Needless to say, I'm a little stumped and am open to suggestions on how to fix this problem, whether its a quick fix or a change in the way I'm trying to record the data.
Thanks in advance,
Mike

Answer 1

Here are the sub VI's that I'm using.  The inner while loop is designed so that the loop will halt immediately when stopped, and not have to finish its current iteration, as the iteration period is intended to be rather long.  I may modify the program to have a programmable start/stop time later, but this is at least my temporary solution.  The purpose of the decimate array function is to seperate out the channel label from the actual data so they can be placed as headers in the Excel function.  The intent was likely not clear with the lack of the SubVI's.  Overall, the display table on the front panel is no longer necessary, it was just for me to see how the table was working in the early stages of development.
The one issue I had with your suggestion is the fact that I the build waveform function only accepts a 1-D array for the waveform input, and with multiple and variable number of channels being used I'm not sure how I could easily manipulate the data I gather into multiple 1-d arrays.
As always the help is appreciated,
Mike
