UTC-6 Timezones being selected at random for Outlook -> Gcal transfers. Some DST some not.

OGCS Version: v2.8.0 and 2.8.1-alpha Installed or Portable: Installed Windows Verson: 10 v1709 (64-bit) Outlook Version Outlook for Office 365 v1902 (64-bit)

Bug Description
OGCS appears to have an issue with the timezone: (UTC-06:00) Central Time (US & Canada)

It appears (US & Canada) is being read by the app as (US %2A Canada) And it doesn’t know what to do with that.

When I perform a full sync, outlook to google calendar, OGCS cannot detect the timezone of the Outlook calendar entry, so it defaults to the first available in the list with UTC of -6 (I am in USA Central time which has DST, but the randomly selected timezone doesn’t always utilize DST). This results in some of the calendar entries showing up in google calendar with the correct time and some an hour later as each is randomly assigned a UTC -6 timezone (some Guatamala, some Managua, and some Central Time - Chicago)

Steps to Reproduce the Issue
Install OGCS 2.8.0 or 2.8.1 Select default outlook calendar Auth google and select calendar Perform full sync Check OGcalsync log and search for timezone

Enhancement checklist by @phw198

• Create XML file to persist custom timezone mappings
• GUI to administrate custom mappings
• During fuzzy logic stage, populate GUI + user confirmation
• In-memory dictionary of existing mappings for use during sync

The prompt/select fix works great. 😃 Thank you. (Sorry for not responding sooner).

Good for me. Just a quick note, once I selected a correspondence for a given timezone, I got a second line with a blank time zone. I gave him the same correspondence and it worked fine.
