Your PC's audio system should beep every second.

This Sidereal Timer will only be accurate if your PC's clock is running an accurate time. Please synchronize you PC to an atomic clock if you need the best accuracy.
[Subtract 30 minutes to accomodate the new Legal Time in Venezuela; DZT: -4.5hrs]


If this is your first Visual Basic 5.0 ActiveX application, viewing it will require you to download two runtime programs from Microsoft's Web site: Msvbvm50.dll (1.3MB) and AsycFilt.dll (116KB) [free]. These are the Visual Basic 5.0 Virtual Machine, and the OLE 2.20 Device Link Libraries.
This will be proposed to you automatically, also if they have to be updated.

Please make sure that in the "Internet Options" of your MS Internet Explorer you have not chosen to disable any ActiveX functionality.
Be aware that this application is not digitally signed, but please trust that I have written and tested this application and have found it harmless to systems; it does not modify any system parameters, and does not write in your disks.
