Hi,

I'm trying to convert from GMT to localtime given a GMT time and an offset
for the locality.  What is the best approach for this?  It should take into
account daylight savings time as well.
  The original problem is that servers dont return always a correct date as
part of their HTTP headers.  Anyone knows a solution to this?

In Windows NT, the time-zone strings are located in the key:

   HKEY_LOCAL_MACHINE\SOFTWARE\
      Microsoft\
      Windows NT\
      CurrentVersion\
      Time Zones.

In Windows 95, the time-zone strings are located in the key:

   HKEY_LOCAL_MACHINE\SOFTWARE\
      Microsoft\
      Windows\
      CurrentVersion\
      Time Zones.

For each time zone, the registry key TZI is formatted as follows:

   LONG       Bias;
   LONG       StandardBias;
   LONG       DaylightBias;
   SYSTEMTIME StandardDate;
   SYSTEMTIME DaylightDate;
