I am hosting a party new years eve. And I am planning on making some cool visuals or stuff involving flourecent tubes for midnight.
my problem is that even though I syncronize the time on my computer so it is quite precise, I experience that it can get up to around 30seconds out of sync.
is there a way to achieve sync that is precise enough that when the telly reach midnight, so does my computer? I know about expensive clocks and such, but is there a way that does not involve expensive hardware and is still precise within a second?
