274.0. "Logged time stamp is 7 hours ahead (WNT, 3.0)" by TKOV60::OKAMURA (H.Okamura PS4-2/EJD3/NSIS, Japan) Wed Apr 16 1997 08:47

I found the problem on ACMSxp 3.0 for WindowsNT.

The problem is that the logged time stamp is 7 hours ahead rather than 
local time. I'll attach the sample log file which captured at 17:51.

I've found two referent to time related function which are 'GetLocalTime()'
and 'strftime()' in STDLRT.DLL. And those two use different structure for
time (i.e. SYSTEMTIME, struct tm).

How does ACMSxp convert SYSTEMTIME to tm structure?

I think that applying time diffential cause this problem.

Thanks,
Hiroaki

We don't see the problem here.  Is the time on your box correct?  Do you have
the timezone set properly?  Check out the Date/Time option in the Control
Panel.

I've confirmed that my timezone was GMT+09:00.

.1>I've found two referent to time related function which are 'GetLocalTime()'

I heard that WindowsNT 4.0 has problem to refer timezone information.

Since Mr. Yasuchika Okubo (WING::OKUBO) has detail information for this issue,
please ask him to get information.

Thanks,

Which version of Visual C++ do you use to build ACMSxp V3.0 for Intel?

Thanks to Ohkubo-san and Horie-san's help, I've found the difference among
V4.0 and V4.2.

I've tested same source code as followings and receive different results.

The produced code by VC++ V4.0 works fine, but V4.2 is not.

According to the result of DUMPBIN, the dependency of Microsoft's library
has been changed.
