GMT confusion during Summer or Daylight time in Outlook calendar

[Guest]

I received an Outlook meeting invitation from a client in the UK. The time
specified by Outlook was 15:00 GMT. I accepted the invitation and my Outlook
calendar assigned the meeting to 8:00 AM MDT. This is what my client
intended. However, this is incorrect, as GMT does not change to British
Summer Time (AKA Daylight Saving Time in the USA). 15:00 GMT is 9:00 AM MDT.


My client tells me he did not specify GMT, that apparently Outlook did. If
Outlook wants to include British Summer Time, then the time zone should be
called either, WET (Western European Time) or WEST (Western European Summer
Time) or WEDT (Western European Daylight Time) or BST (British Summer Time).
Certainly, it should not be called GMT, UTC, Zulu, etc. These times are all
seasonally invariant and never include "Summer" or "Daylight" time.

This caused confusion, requiring several emails back and forth to confirm
what time my client really meant.

Thoughts?

Thanks in advance.

Outlook does everything in GMT and time zone offsets. If the computers time
zone is properly configured, outlook will know the time is gmt +1.
