You really should start your question in English - or in the Spanish regional board…

 

  1. You may read the system time at start of your VI, then you add the loop iteration time (in seconds) to that timestamp with each iteration. This way you only need to read the system timestamp once… (This may introduce some rounding issues, so the accumulated time value may still differ from "real" time.)
  2. Use a GPS device to deliver the correct time…
  3. Read the timestamp from a webservice…

(Item 2 and 3 use external resources to get timestamps, so they are not influenced by the computer local time.)

Best regards,
