wrong time?

hey,
i'm a mech engg student doing proj in LV.... i've attached the VI (http://www.wikiupload.com/download_page.php?id=91501) code i've worked on so far... here are some questions i've got on it(i'm quite a novice to lv)
 
1. when i build a table with include time option checked  i get the time/date starting from 5:30:0.0 1904... how do i change this to my system time?
 
2. i've used LED as a warning light to glow when a value exceeds a threshold.. can i also include a sound to go off...how?
 
thanx

  1. Open the "simulate signal" express VI and select absolute time for the time stamp.
  2. branch the wire going to the LED and wire it to a small case structure. Inside the TRUE case, place a simple beep, or play a waveform, etc.
