I would like to do this as I think it affects some of my candle charts.

If so, where do you find the exact time? (to the second at least).

My platform has a clock of its own, but presumably most systems are sync'ed to NIST's atomic clock in Colorado.

You can sync your own PC (presumably you're using Windows) to that by

clicking on the clock --> Change date and time settings...-->Internet Time tab -->Change settings...-->select time.nist.gov from the list and click Update Now

A better option is to disable the genuine W32Time service and use something like Meinberg NTP.
Then choose us.pool.ntp.org as main NTP server pool and you'll be god to go.
The standard Windows time service with the default configuration is not good enough for trading purposes.

Well, you learn something every day - I wasn't aware of this. Thanks Sam.

Thanks! @xplorer and @sam028

I use Dimension 4, free, easy and it rocks.

Thinking Man Software - Dimension 4 v5.3

Agree with Sam, I always found the Windows computer clock would go out of sync pretty quickly.
I tried Dimension4 about a year ago or so when I was still on Windows 7 but I kept having problems with it. It seemed to install okay and work initially but would then stop working.
I then switched to the Meinberg and had no problems on Windows 7 or now on Windows 10. Meinberg has a comprehensive setup and trouble shooting page which at first glance looks a little intimidating but was easy to follow and it has worked flawlessly in the background ever since.

Maybe i missed something...

But, have you experienced a failure ? or an edge ? being milliseconds alignee with an atomic clock ?

Or is this discussion about something different ?
In general i will avoid trading shortly before and shortly after important economic new events
and still from time to time i get toasted (like this week in 6b, not in a bad way, but i missed
a major series or 'triggers'... that were not flagged

Would be keen to get your ideas about this..

i'm not on HFT
a second does not make any difference..

Miliseconds doesn't matter to me, but I do want to be as close as possible at least to the second.

This question came up because last week while watching Bloomberg I was at 9:31+ and they were talking about how the market open is in about 15-20 seconds. I know there is a delay int he stream, but I figured a 2 minute delay was probably not right.

This won't make a big difference outside of critical times (open, FOMC announcements, etc.). But it could make a small change into what my candles look like, specially on high volatile environments. I read the candles and the wicks to determine the 'feel' of the market so it could make a difference.

The difference is marginal at best, but the effort to change it is minimal.

A marginal gain for minimal effort? I'll take that improvement any day of the week.

Hope this clears things up.
