Convert a Date/Time String into Timestamp Data in LabVIEW

Use the Scan from String VI

1. On your LabVIEW VI block diagram, right-click to open the Functions Palette and navigate to Programming >> String >> Scan from String.
2. Configure that Scan from String VI
   1. Right-click the Scan from String VI and select Edit Scan String from the dropdown menu.
   2. From the Selected operation menu, select Scan time stamp. 
   3. Customize the string format using the Corresponding scan string textbox. Use the Time Stamp Format Codes as guidance to match the format of your string data.
      • The example shown in this article uses the following format string: %<%I:%M:%S%3u %p%m/%d/%Y>T
      • An example input string that works with the example shown in the article is: 4:43:25.628 pm 3/11/2024
      • Note: If you leave the format string as %T, LabVIEW will guess based on commonly used formats.
   4. Select OK. Notice that a string constant matching the configuration set in the previous set is automatically wired to the format string input.
3. Wire in your string data/type data into the input string.
4. Right-click the output 1 node and select Create Indicator.

Use NumText.Text property of a Time Stamp indicator

3. Right-click the Property Node and select Change All to Write.
4. Right-click the Time Stamp indicator and select Properties.
5. Navigate to the Display Format tab to customize the time and date output format, then select OK.
