The AutoDST flag is ON and the time service is running, but your testing has caused you to transition from DST to DST, so no clock adjustment is made. The AutoDST flag is ON but you're not running the time service to actually handle the DST transition.ģ. Also, the system flag returned from GetTimeZoneInformation() indicates whether the system *thinks* it's currently keeping DST or standard time. There's a time service and an associated flag that controls DST adjustment. I am seeking any technical expertise in resolving it. I hope I did my best to diagnose and fix the issue which was partially successful sans the DST issue. LblTimeVal3.Text = string.Format("", uCeRTOffset, dtRaw, dtRaw.ToUniversalTime()) LblTimeVal2.Text = () ĭateTime dtRaw = dtWindowsEpoch.AddTicks((long)(uCeRawTime + uCeRTOffset) * TimeSpan.TicksPerMillisecond) I wrote a small test program and verified the System time calculated from 'GetCeGetRawTimeUtc' against () Int nErrCode = Marshal.GetLastWin32Error() St.wMilliseconds = (ushort)dtUtc.Millisecond Public bool SetWinCESetSystemTime(System.DateTime dtUtc) WinCEGetRawTimeOffset(ref uCeRTOffset) //offset, to be added to the CERawTimeĭtRawUtc = (dtWindowsEpoch.AddTicks((long)((uCeRawTime + uCeRTOffset) * TimeSpan.TicksPerMillisecond))).ToUniversalTime() WinCEGetRawTime(ref uCeRawTime) //number of 100 nanoseconds since 1601, not POSIX epoch (1970) Private void GetCeGetRawTimeUtc(ref ulong uTime) String strErrMsg = "UpdateSystemTime:" + ex.Message //Write to log Private extern static bool WinCEGetRawTimeOffset(ref ulong ui64Offset) ĭateTime dtWindowsEpoch = new DateTime(1601, 1, 1, 0, 0, 0, DateTimeKind.Unspecified) //Windows Epoch (1601) Private extern static bool WinCEGetRawTime(ref ulong ui64Millsec) Private extern static void WinCEGetLocalTime(ref SYSTEMTIME st) Private extern static bool WinCESetSystemTime(ref SYSTEMTIME st) Private extern static void WinCEGetSystemTime(ref SYSTEMTIME st)
Here is the implementation in .NET CF using C#: Here is how I set the system time at regular interval as a workaround:īOOL CeGetRawTime(ULONGLONG * pui64Millsec) īOOL CeGetRawTimeOffset(LONGLONG * pi64Offset) īOOL SetSystemTime(const SYSTEMTIME* lpSystemTime)
I conducted a test at the samples and found out that the time is not changing for either The time zone is set for the time zone that participates in the day light saving and the registry () been set. It appeared to be fixed the issue of time drifting however the clock did not forward when the DST began even though I worked on a work around and it has been decided to set the date and time at regular interval with a background process. Than three samples of our embedded devices proved it. We have noticed that the system time is drifting ahead to a few seconds in days and minutes in a couple of weeks and the test conducted with more We have BSP developed for our embedded device by our vendo for my application running on Windows CE 6.0.
