Hi,

Is there an easy way to convert GMT times to local times and vice versa? Do
I have to use the extended mapi TimeZone property? I use VB6 and redemption.

In Redemption :-) - that's what Roland said he is using.
There is really nothing magic about these functions, just
FileTimeToLocalFileTime() and LocalFileTimeToFileTime() Win API functions
with some conversion between FILETIME/SYSTEMTIME/DATETIME.

Actually I think some extra little magic is required to account for Day
Light savings time .... or at least I needed to account for this ... I
remember having all sorts of problems if the data I was converting was in
Day Light Savings and the current time was not Daylight Savings ..
 
Thanks Dmitry,

I did look for a mapiutils method on your website but is's not listed in on
the MAPIutils page. Consider upgrading the page...
While you are doing this also consider adding an explanation on the
mapitables page of the RELOP constants. I couldn't find them and it took me
a while to figure them out (ok, I'm a simple VB programmer...).
