DASL Filter function?

I am trying to figure out how to use the "undocumented" Today(S) function.

Basically I have about 10 search folders that make use of most of these:

%yesterday

%today

%tomorrow

%last7days

%next7days

%lastweek

%thisweek

%nextweek

%lastmonth

%thismonth

%nextmonth

So I am also hoping that these functions also allow for passing of a (S)

seconds parameter. The reason I am hoping to do this is to pre-adjust my UTC

DateTime field "MileStone1UTC" so that it will be normalized into local

date/time.

e.g.

"http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/MileStone1UTC"

= Today(46800)

e.g.

"http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/MileStone1UTC"

= Tomorrow(46800)

However it doesn't work. Anyone know what will here?

Maybe if I knew what Today(0) equated to I could use that if it was an exact

time such as Saturday, January 30, 12:00 AM.

Then I could use:

MileStone1UTC >= Today(0+46800) AND MileStone1UTC <

Today(0+46800+(24*60*60))

where 46800 is 13 hours in my case -- that is the UTC offset from local

time.

Outlook SQL DASL syntax - an update

Here's an update to my previous blog entry on Doing more with Outlook filter

and SQL DASL syntax.

I had some great feedback from my previous posting, there is obviously a

need for more information about how to "do stuff" with Outlook filters.

Special thanks to Patrick for a very useful message, which showed me how to

use dynamic dates in Outlook filter queries. Previously I thought this was

impossible! Patrick's trick :)o) is to use the today(S) function with a

parameter in seconds (S). The parameter gives a positive or negative offset

from today and can be used to check the Due Date of tasks (or any other date

test you like).

Here is Patrick's example which he uses on the Tasks folder:

(

("http://schemas.microsoft.com/mapi/id/{00062003-0000-0000-C000-000000000046}/811c000b"=0) AND(NOT("http://schemas.microsoft.com/mapi/id/{00062003-0000-0000-C000-000000000046}/81050040" IS NULL)) AND("http://schemas.microsoft.com/mapi/id/{00062003-0000-0000-C000-000000000046}/81050040" <= today(864000)))When applied to a task folder, this shows 'notcompleted' tasks that have aDue Date set in the next 10 days from today.Thissame technique should be useful for filtering on received date (etc) onemailfolders and others.-Snip end-=================================================================================

I believe that Today(n) is the only one that allows that, but with

undocumented things they aren't documented and they can't necessarily be

relied on in all versions. I think Today(n) works across the board, but I've

never tested it.

I think you're going to have to test what Today(0) is for you. My guess is

that it's not something you would be able to rely on as a hard-coded value

except for users in the exact same time zone as you. If the time zone

changes I'd expect the offset value to change. I'd also expect it to change

with daylight savings time changes. My impression is this is not the best

way to go if you intend to distribute your code.

What I'd do is instead massage the data in that user defined field so it's

correct. Convert it to local time before you store it in the data field, or

run one-time code to convert existing data and you're done and don't have to

worry about this sort of thing.

Yes I tend to agree.

The only downside to creating an additional user-defined field called

MileStone1LocalTime is if the add-on is stored on somebody'slaptop and they

tend to be a jet-setter (e.g. travelling salesperson) and frequently enter

different timezones. Then the hard-coded local time is no longer relevent.

I suppose the way around this is to store the UTC offset in settings and

check that it is the same on Addin startup. If it's not I'd probably need a

messagebox saying "time-zone adjustments need to be made -- this can take a

few minutes." and then proceed to loop through all emails in all folders,

updating the user-defined field value and saving each one. This would need

to be on the main thread since if I tried to do it in the background it

would appear to hang.

I think you're overthinking this.

If a user is in Florida and their settings are correct for local time zone

the data is stored as UTC, compensated by the local time zone offset. If the

user flies to California and they want UTC times to be correct for that

local time zone they can set the Outlook time zone, add an alternate time

zone and/or change the Windows time zone. Then everything is correct for

local time again.

This is the exact same thing for every single date field in every Outlook

item. If when the date values are entered the time zones are correct the

data is correct in UTC and that's all you can ever expect. If the user

changes time zones and doesn't update their settings every single one of

their date fields will be off by some offset to local time.
