texte = I have confirmed this to be a bug with the Windows builds of WebDNA. I am testing the WebDNA 4.5 release build on a machine that is set to PST (PDT), and the DATE header generated by the sendmail thread is off by one hour as reported.It is true that the engine does not make the call to _tzset() before the call to get the system time. However, the call to _tzset() will only have an effect if there is a TZ environment variable set on the system. If there is a TZ environment variable set, then the _tzset() call will use the TZ value to set other environment variables that store information related to time zone and 'daylight savings' state. If the TZ environment variable is not set, then the next call to tzset(), ftime() or localtime() will populate the other environment variables based upon the Control Panel's Date/Time application settings. In my case, adding the _tzset() call did not fix the problem.I looks like the fix involves simply checking the data structure returned from localtime() and checking the state of the daylight-savings-time flag, and then making the necessary adjustments to the GMT offset. I am currently testing this fix. If all goes well, we will release a patch for the Windows WebDNA build soon.> -----Original Message----- > From: WebCatalog Talk > [mailto:WebDNA-Talk@talk.smithmicro.com]On Behalf > Of John Peacock > Sent: Tuesday, September 10, 2002 6:53 AM > To: WebCatalog Talk > Subject: Re: One Hour Email > > > Kenneth Grome wrote: > > Does this mean that the server admin has configured something > > improperly, and that improper configuration is more than likely the > > cause of this problem? > > > > OK, my face is red now: > > > Return-path:
