Before I start a flight I always set the UTC time to the actual real world time before entering the sim but through the course of 2-6 hours of flying the time begins to differ by sometimes more than 30-40 mins is there a way to keep that from happening? I ask because I fly on VATSIM and when I give progress reports or need info for arrival times on the FMC it throws things off for ATC and myself.

Did you pause the sim, because if you do then the sim's internal clock will stop?

Try this one:Check the registry:[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]"RealTimeIsUniversal"=dword:00000001Reboot after change

Thanks for the quick response i will try the reg tweak!

There is payware called fsrealtime.

My FS loads with the time always 2 hours ahead of my time sone. I have the option set to use my time. I have to click the reset every time i start a flight, anyone lese have a problem like this?

This will fix all problems! http://www.3dsoftworks.net/products/fsrealtime/

Wish that were true. I tried FSrealtime. Did not solve the problem. Something externally is telling FSX the time has changed.

i think it´s something with this ngx and the clock. my clock is always in advance 1or 2 minutes short after loading the plane. during long flights the minutes increase.if i use the fsupic sync option fsx has to reload every 2 minutes. this happnes only in the ngx. any ideas? tarik

I use FSRealTime, it works great for me and my NGX

The time difference is frusterating for me too. I always set zulu before my flight and I have to keep going back in and resetting it. Ugh.I don't know why we have to pay for an addon that FSX should do automatically like it suppose to if you have "use system time" checked.It's not the NGX. It's all aircraft for me.
