Setting current system time?

Hello everybody,

First I'd like to thank Ken Lee for the tip of MicroAngelo (nice app).

Here the millon dolar question:

Have anyone set the system time and date from a dolphin application?
How do you do this?

I haven't found how to do this yet.

regards,

Sebastian

If you mean setting the time and date to add a time stamp then this is
straightforward:-

Time dateAndTimeNow

If you mean resetting the system date and time from within a Dolphin
Application I guess this could be done - you would need to add the Windows
message SetSystemTime message to the KernalLibrary and I think you would
also have to add system privilages to the calling process

RE: Setting current system time?

Hi David,

yes, I need to set the system time to sincronize the time and date
between differents dolphin applicationd on a LAN. I set it in one app and
they comunicate each other through sockets an set the same system time.

I'm affraid I don't have been using the kernel before. How do I add that
message and where I can get info about the parameters of that call? I don't
know how to prepare the data.

thanks, regards

Sebastian

RE: Setting current system time?

This appears to work on my Win98 machine:

Add the following method to KernelLibrary

setSystemTime: aSYSTEMTIME
"Sets the local date and time.
BOOL SetSystemTime(
CONST SYSTEMTIME *lpSystemTime // address of system
time to set
);"

< stdcall: bool SetSystemTime SYSTEMTIME* >
^self invalidCall

In a workspace the following sets the clock forward by 1 hour

time:=SYSTEMTIME now.
time wHour:(time wHour +1).
KernelLibrary default setSystemTime:time

Hope this helps

RE: Setting current system time? (strange results)

Hi David,

I think your method works but we are missing something here.

I've added your >>setSystemTime: to the kernel, then I evaluate the
workspace that you provided me.

time := SYSTEMTIME now. a SYSTEMTIME(18:51:01, Martes, 06 de Febrero de
2001)
time wHour:(time wHour +1). a SYSTEMTIME(19:51:01, Martes, 06 de Febrero
de 2001)

KernelLibrary default setSystemTime:time. true

Time now 16:51:19 this is the pathologic one.

my system time goes 2 hours backwards.

I runnin it on a win98 (spanish version). Could the local settings be
involved?

regards

Sebastian

Strange - I'm not sure what is happening here - it seems to work correctly
on my work and home machines ( both running Win98SE -English version).
Perhaps someone else would try it?

Re: Setting current system time? (strange results)

Hi David and Sebastian,

I think the problem is that you are asking for a local time, and then
setting "system" time which is Universal time. Have a look at;

http://msdn.microsoft.com/library/psdk/sysmgmt/time_5gh1.htm
http://msdn.microsoft.com/library/psdk/sysmgmt/time_7xr9.htm

Instead of using KernelLibrary>>setSystemTime: use
KernelLibrary>>setLocalTime:

David, do you live in the time zone where UTC=Local time?

Steve

SYSTEMTIME now answers local time, and setSystemTime set

Thanks Steve - I do indeed live in the GMT timezone ( north east
England) and so my local time would =UTC.
