[Wine] Timezone not recognised kludge

[llewro]

This is for Wine 1.1.28 compiled under a customised personal Linux based on Slackware.

When running winefile from a terminal, get a line:

"fixme:ntdll:find_reg_tz_info Can't find matching timezone information in the registry for bias -720, std (d/m/y): 5/04/2009, dlt (d/m/y): 27/09/2009"

Wine source: ../dlls/ntdll/time.c holds the function "find_reg_tz_info".

Running: # WINEDEBUG=trace+ntdll wine winefile

gives a dump of the trace statements for this function and shows the registry timezone information for timezones as it scans each. It cannot find a match.

This I kind of expect as the TZ info for NZ has been altered recently so the wine source ../tools/wine.inf.in is incorrect.

To do a quick fix I edited the registry timezone info for NZ and changed the day, month and hour to conform to the new values.

However this still did not work!.

Only when I changed the year to 2009 did it work ok.

I think this is basically a bug in the ntdll, time.c functions as the year should not figure in the calculations?.

A resulting reg file fix follows, with comments attached:
