[Aavso-photometry] GPS or internet time?

[Peter Nelson]

Hello Yenal,

You should try Symmtime from Symmetricom (http:// 
www.symmetricom.com/). This program is free, and synchronizes your  
computer with a time standard over the internet.  It makes allowances  
for travel time from your computer to the server and back again.

I have found my times to be within 0.2 sec fairly consistantly,  
compared with a non computer time standard.

Kind regards
Peter
