HOW DO I ACHIEVE A TIME STAMP, IN THE FIRST COLUMN OF MY SPREADSHEET IN EXCEL,SHOWING THE TIME INTERVAL, INCREASED BY THE SCAN RATE ?

[jbc]

FROM AI START VI TO FORMAT AND APPEND VI TO CONCATENATE STRINGS,SECOND INPUT IS TAB,THEN EVEY OTHER ONE IS TAB. THIRD AND FIFTH INPUT IS ATTACHED TO GET DATE/ TIME VI, THEN END OF LINE, THEN CHANNEL 0; TAB; CHANNEL 1;TAB, AND SO ON THROUGH CHANNEL 7. THEN THE LAST INPUT IS END OF LINE. ON THE SPREADSHEET I RECIEVE THE SCAN RATE, THEN THE DATE ,THEN THE TIME; ALL ON THE FIRST ROW. THE NEXT ROW HAS THE COLUMN LABLES, AND DATA GOES TO THE CORRECT COLUMN. BUT NO TIME STAMP COLUMN. I WOULD LIKE IT TO BE IN COLUMN "A" EVEN WITH THE FIRST ROW OF DATA. EX." 10:01:01 200 300 400
10:01:03 200 300 400
THANK YOU
FOR YOUR HELP, JOE BOB CRAIN

I think the best way is to generate an array of time values to send to your spreadsheet BEFORE channel 0 data.
To generate the array you can use Ramp Pattern.vi from 0 to 'Actual Scan Rate' (from AI Start) * number of scans performed.
That way in your spreadsheet you will have the first line same as now, next the columns with time(secs), channel 0, channel 1... channel 7.
If you need the time column with date and time string, you can use Get Date/Time in Seconds.vi when you begin acquisition, then sum the seconds obtained to the array calculated as above and next use Format Date/Time String.vi to obtain the time stamp you need, next build array of time stamps and sent to your spreadsheet.
Hope this helps
