Hi, SC, A couple of "time" related questions: 1. A message log normally shows "time difference to Server" in whole seconds. Is it possible to change the resolution to 2 decimals? 2. Manuals have references to two date/time sync settings: - Global Settings -> Set System Time from Server - Data and Trade Service -> Timestamp using local computer clock https://www.sierrachart.com/index.php?l=doc/helpdetails38.html Both would be very useful, but I cannot find them in the relevant menus. I am using IB and SC 1400. Please support. H.

OK, I upgraded to ver.1405 and can now see "Set System Date-time from server" under Global settings. (WHY is there no Change Log?? This is not such a minor development. What other changes have there been from v1401 to 1405?) Under "General Settings" there is now also an option to "Periodically Set System Date-Time from server" - WHICH IS NOT DOCUMENTED. So, how often would this last option re-sync local computer clock? Still could not find "Timestamp using local computer clock" option in the Data and Trading service... I tried to re-sync time with SC's "Set system Date-time" from server and found that it is ahead of the clock vs. a Stratum One time provider in NYC that I normally sync my VPS in NYC with(clock.nyc.he.net) - http://support.ntp.org/bin/view/Servers/StratumOneTimeServers?sortcol=0;table=1;up=0#sorted_table - most often by 1069-1071ms(!) and sometimes by around 60-70ms.(RTT to SC server in Europe is 141ms). From the other hand, IB's end-of-minutes are mostly consistent with the sync I use. Would greatly appreciate your thoughts/suggestions/recommendations on the most accurate time syncing. How do brokers sync time?

- Data and Trade Service -> Timestamp using local computer clock This setting does not exist for Interactive Brokers. The documentation has been clarified on the subject. In the case of Interactive Brokers your local computer clock is used for time stamping. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Under "General Settings" there is now also an option to "Periodically Set System Date-Time from server" - WHICH IS NOT DOCUMENTED. We are documenting this now. The documentation will answer your questions. We have limited time to be updating the What is New page. Our primary focus is continuing with development and updating the main documentation.

But how are current users supposed to discover new functionality? By re-clicking and closely looking through all of SC menus and submenus and then reverting to the manual? I understand time constraints and only covering key changes...but at least those. 1. A message log normally shows "time difference to Server" in whole seconds. Is it possible to change the resolution to 2 decimals?

New "Set system date-time from server" functionality provides a similar message log with the necessary detail..

However, in the next release, when you have Global Settings >> General Settings >> Periodically Set System Date-Time from Server, this will be done on startup and the time from the server with milliseconds is given.

This is an example of what you will see in the Message Log in the next release when there is a time synchronization: Received Date-time from server.

Okay so I thought I would give this setting a go under v1406 as my computer clock was always about 2 seconds slower than SC time bars. I use W10 OS and it is very difficult to change the frequency with which W10 will sync with Internet Time (I think the default is weekly). Anyhow, here is the extract from my SC log following selecting this option under General Settings: HTTP connection to www.sierrachart.com:80 (0) \| Resolved address sierrachart.com to IP 5.9.8.236. \| 2016-05-09 10:53:53 HTTP connection to www.sierrachart.com:80 (75) \| Connected. \| 2016-05-09 10:53:53 HTTP connection to www.sierrachart.com:80 (75) \| Closed.

Isn't W10 just wonderful!!!! So much of it is locked down. I have read about some hacks where others have mucked around with the registry and other components to trick the OS into time syncing more frequently. Guess I will try one of those. You might want to add to your documentation that this SC setting will not work under W10.

We would not add that to the documentation at this time because we do not know whether this is specific to a standard installation of Windows 10. Although probably it is.

Once I set the SierraChart.exe file (or shortcut to it) to "Run as Administrator") it works fine on all my Windows 10 PCs. And I have UAC turned off, but I don't know if that matters.
