hi, in recent update of gurux , It can't Parse Persian date Correctly . in previous versions ,it was working greatly.

it has error on C# version and GxDlmsDirector.

Packet examples :

TX: 7E A0 1C 00 02 76 71 03 54 A8 19 E6 E6 00 C0 01 C1 00 08 00 00 01 00 00 FF 02 00 60 1A 7E

now it gives Error :

I think the problem raises for month with 31 days . for example in above packets, in Persian 2nd month have 31 days and raises error. but other dates works greatly.

do you have any Idea, what we can do or is there anything that you can change in code ?

If you can add Calendar to GXDLMSSettings class and use below constructor of DateTime :

public DateTime(int year, int month, int day, int hour, int minute, int second, Calendar calendar)

that has calendar in in Conversion, I think all the problems will be solved

Hi,

No changes have been made to the date and time for a long time. Application is using the default calendar when the date-time is read from the meter.

The date is Yekshanbeh: 31. Ordibehesht 1402. Is that correct?
What is your time zone?

Yes, it.'s correct date.
Timezome is : +3:30 Tehran

Is there any way to change calendar (set) for this?

Hi,

Calendar settings are defined in Windows and correct settings are given as a parameter. You can try to change settings from the Windows regional settings.

Are you using Windows 10 or 11? The same environment is installed and I believe that this can be fixed if it can be repeated.

BR,

No we are using windows server 2012, and I need to set gurux calendar from code. Setting current thread culture also don't slove the problem.
Any ideas will be appreciated.

hi,
Is it possible for you to use DateTime overloads with calendar input in GxCommon ?
I mean use :
new DateTime(year, month, day, hours, minutes, seconds, milliseconds,Thread.CurrentThread.CurrentCulture.Calendar)

instead of :
new DateTime(year, month, day, hours, minutes, seconds, milliseconds)

or :
new DateTime(year, month, day, hours, minutes, seconds, milliseconds, Thread.CurrentThread.CurrentCulture.Calendar, DateTimeKind.Local)

instead of :
new DateTime(year, month, day, hours, minutes, seconds, milliseconds, DateTimeKind.Local)

Hi,

This doesn't help when you are reading data from the meter because it's not possible to set the calendar for the GXDLMSClient.

If you run dotnet --version what is the output?

there is no need to set calendar for the GXDLMSClient. we can use custume Culture class that has calendar as needed, and set for thread culture. but because you use this overloads of "new DateTime" that does not have Calendar in there inputs,then .net does not use thread calendar for them.

dotnet --version
7.0.203
