Re: Time Zone Error Message with DWA

This error can be caused by either of the following:

Your workstation and the Domino Server are both in the same time zone, but 
there is a mismatch between client and server.  Either your workstation or 
the server does not have the "Automatically Adjust  Clock for Daylight 
Saving Changes" option selected in the Date/Time setting in the Windows 
Control Panel.  The server and workstation operating systems (OS) must 
both be either observing or not observing Daylight Saving Time (DST).

- OR -

Your workstation and server time zone match AND they are both NOT 
observing DST  AND DWA opens to the Welcome Page when you launch it.  This 
issue has been reported to Quality Engineering as SPR# FMWI69VTPZ and has 
been fixed in Domino 6.5.5 and 7.0.1. The solution is detailed below the 
workaround.


As a workaround you can:

Open the Domino Server's Configuration document, change to the Domino Web 
Access tab, and under the Start Up View section change the 'When Opening 
Domino Web Access, Open To' field from "Welcome" to "Mail".

-or-

In DWA if you have previously saved your Preferences, then open the 
Preferences dialog again, go to Other and change the 'Display this View 
when Starting' choice from "Welcome" to "Mail".

In one customer's case, the workaround did not work unless the Microsoft 
Windows server had the Microsoft path KB928388 applied.

Beginning in DWA 6.5.5 and 7.0.1, two options exist to resolve the issue 
where DWA's default time zone settings do not correspond to the settings 
on the server's operating system.  In some scenarios it might make sense 
to use one over the other.

Option 1:  Modify the Custom_JS form in DWA mail template (iNotes6.ntf or 
DWA7.ntf) and Forms file (Forms6.nsf or Forms7.nsf)

The first option involves customizing the API_TimeZones() section in the 
Custom_JS form of the DWA mail template and the Forms file to include the 
new or updated time zone information observed by the Operating System. 
Using the Domino Designer, open the Formsx.nsf database. Open the 
Custom_JS form and locate the API_TimeZones() section.  The additional 
code entries must be located prior to the line "return (a_Table);"

Once the new time zone settings are added, the HTTP task will need to be 
restarted for the new settings to become available. 

The following example will provide a new time zone option at the top of 
the drop-down dialog for DWA users under Preferences > Calendar > Time 
zone called "(GMT+2:00) Jerusalem (Customized)" which allows for Daylight 
Saving Time to be observed.

The default DWA option, "(GMT+2:00) Jerusalem, Harare, Pretoria" does NOT 
observe Daylight Saving Time, and can therefore generate the "Your 
timezone setting is different from your operating system's current one..." 
error if used, as well as cause Calendar entries to appear off by an hour 
during Daylight Saving Time.

EXAMPLE:
a_Table[a_Table.length] = ["Jerusalem Custom", "Jerusalem Custom", 
"(GMT+02:00) Jerusalem (Customized)", -2, true, "4, 1, 6, 10, 2, 1"];

The first 3 arguments are Labels that may be customized for clarity as 
needed.  Care should be taken in the naming, though, because if a setting 
by the same name already exists in DWA, the custom setting will override 
it... which may or may not be desirable.

The remaining arguments indicate the following...

-2
Offset from GMT
true
Observe DST
"4, 1, 6, 10, 2, 1"
start month, start week, start day, end month, end week, end day of DST; 
ie, DST begins the first Saturday in April, and ends the second Sunday in 
October.

Note: These values correspond to what would be found in the DSTLAW 
parameter in a notes.ini


Option 2: Add iNotes_WA_UseServerTZSettings=1 to the Domino server's 
notes.ini

By adding iNotes_WA_UseServerTZSettings=1 to the server's notes.ini, the 
Timezone settings used by the server operating system will automatically 
appear at the bottom of the DWA Preferences > Calendar > Time Zone 
drop-down list.

Using the above example, this would add the entry, "(GMT+02:00) Israel" 
directly beneath "(GMT+13:00) Nuku'alofa" in the drop-down.

Note: The above INI parameter was introduced in Domino 6.5.5 and 7.0.

Supporting Information:

When to use API_TimeZones() versus the iNotes_WA_UseServerTZSettings:

While both options will allow for customized time zone configurations, it 
makes more sense to use one over the other, depending on the situation.

For example, if the start and/or end of Daylight Saving Time changes from 
one year to the next (as in, it may not always be the first Saturday of 
April), then it may make more sense to use the 
iNotes_WA_UseServerTZSettings=1 setting on the server, so that repeated 
modifications to the Custom_JS form do not have to occur to account for 
the year to year change.

Likewise, if numerous geographies are involved with unique TimeZone 
settings that stay constant from year to year, then it may make more sense 
to add each of those custom settings to the Custom_JS form, to make each 
of the custom options available to DWA users at once.

Time Zone Error Message with DWA






Has anyone seen any issues where everytime you start DWA it says your Time 

Zone doesn't match your OS Time Zone, even though DWA is set to use the OS 

Time Zone?  Is this possibly due to the recent MS patch for XP for the new 

Time Zone rules?

Thanks in advance,
