How are you reading the date? DateTime.Now?

It sounds like it's a timezone issue. The CF caches the current DateTime
(at least in 1.0 it did), so if you call out to set the time, DateTime.Now will always be wrong from that point on. Without seeing code, I can't say for sure what might be goping wrong though. -- Chris Tacke, eMVP Join the Embedded Developer Community http://community.opennetcf.com [quoted text, click to view] "tony" <daylor@netvision.net.il> wrote in message news:flbdoo$9el$1@news2.netvision.net.il... > Hi, > > till now i used DateTime.Now , after reading a little , i tried also > GetLocalTime > but it return the same wrong value of 1/1/2008. > > very annoying. > > any ideas ? > > thanks for your help. > > > "<ctacke/>" <ctacke[at]opennetcf[dot]com> wrote in message > news:elrKUz9SIHA.1184@TK2MSFTNGP04.phx.gbl... >> How are you reading the date?

HI,
strange bug from device that work for 6 month .. everytime the device is starting, the user set the date and time. today, the user set 31/12/2007 14:00 and in the main menu the date was 01/01/2008 . what am i missing here ? the device is not connected to internet or any network. and im using OpenNETCF.Win32.DateTimeEx.SetLocalTime. and net compact 1.0 thanking in advance.
Hi,
till now i used DateTime.Now , after reading a little , i tried also GetLocalTime but it return the same wrong value of 1/1/2008. very annoying. any ideas ? thanks for your help.

except from SetLocalTime and GetLocalTime
i need to call other functions ? how do i set the timezone, and to what value ? i can build small program to test it and send the code, just tell me what to test ? (SetLocalTime, GetLocalTime,DateTime.Now) thanking in advance.

SetTimezoneInformation() will set the time zone (OpenNETCF has a wrapper for
this, too). Check what the Control Panel Date/Time applet says about the time zone. Have you tried setting the date/time *that* way and seeing if it works? That would point more-definitely to either a) your code is wrong, or b) there is a time zone issue. Paul T.

Hi
I am facing a similar issue. Though my device works on windows CE 6.0 but i think the problem is related. my device was also working fine since last few months but now from 1st Jan, the date that is getting set is one day ahead of what i m trying to set. the hours and minutes are getting set correctly. I am using SetLocalTime to set the time. As suggested, i tried setting the date using Date/Time applet in control panel, but the behaviour is the same. I am also setting the timezone registry in platform.reg file to set my timezone after every cold boot. Any help is appreciated. Thanks
So, you're getting a different value from DateTime.Now than what you
actually see on the Date/Time Control Panel applet? Have you tried exiting all .NET CF applications and restarting them to see if that changes? When you set the date/time via the Control Panel to today, the current time, it automatically is shifting the date around on you? That's not happening to me (I don't have a CE6 device laying around, but it's working perfectly in CE5). What time zone are you set for? Paul T.

Thanks Paul for the reply. Please find the answers to your Questions.
-------you're getting a different value from DateTime.Now than what you actually see on the Date/Time Control Panel applet? No I see the same value in both the cases but it is different from what I am setting. I am using GetLocalTime API. -------Have you tried exiting all .NET CF applications and restarting them to see if that changes? Yes. I have restarted the device and applications and the problem is still there. ------- When you set the date/time via the Control Panel to today, the current time, it automatically is shifting the date aound on you? Yes. If I set the date for today, it sets the date for tomorrow. ------- What time zone are you set for? India Standard Time. There is no daylight saving in this time zone. Code snippet. ////////////////////////////////////////////////////////// SYSTEMTIME st,st1; st.wYear = 2008; st.wMonth = 1; st.wDate = 4; ..... ..... ::SetLocalTime(&st); ::SetLocalTime(&st); // read somewhere that i need to do this twice. ::GetLocalTime(&st1); printf("st1.wDay = %d\r\n",st1.wDay);// prints 5 here. ////////////////////////////////////////////////////////// Thanks Abhishek

If I set the date for today, it sets the date for tomorrow. You're really telling me that, when you change the date/time on the control panel, it doesn't accept what you enter, but instead changes it to another date? Sorry, I can't believe that.

No. This has the feel of you having some service running in the background on this unit, the time service, maybe, and it doing something when you change the date/time. Check what is running on the device besides your programs. Paul T.
Hi Paul,
[quoted text, click to view] > st.wDate = 4; that was a typo. its wDay.I will check on the services thing. Thanks for the reply,
