[FoxyTab] Clarity regarding UTC vs GMT #510

Open ejm554 opened 1 year ago

I like in the United States, and I want my FoxyTab to display the current time in UTC, the international time standard. I had chosen the "London" option several months ago because it had "GMT/UTC" listed next to it:

I assumed that this time zone descriptor to mean that these two were equivalent. However, as we entered summer, I discovered that this assumption was wrong. It appears to be showing BST (British Summer Time):

I think I fixed the problem by choosing the "GMT (no daylight savings)" option:

That said, I'm confused by the way the time zones are listed relative to GMT, rather than UTC, the more common international standard (at least in the computing world).

I wonder if the list of options could benefit from some polishing, such as the following:

I know that time zones can be real pain to work with in a universal way, but thanks for considering these ideas anyway. :-)

Allow some customization of how times shown in FoxyTab, e.g., allow a user to show "Edinburgh" instead of just "London."

It should be possible. I will look into it when I start working on an update.

Use UTC in favor of GMT in the list of options when describing differences between cities.

The standard has been GMT for a long time. Furthermore, ...

The Difference Between GMT and UTC

Greenwich Mean Time (GMT) is often interchanged or confused with Coordinated Universal Time (UTC). But GMT is a time zone and UTC is a time standard.

Although GMT and UTC share the same current time in practice, there is a basic difference between the two:

  • GMT is a time zone officially used in some European and African countries. The time can be displayed using both the 24-hour format (0 - 24) or the 12-hour format (1 - 12 am/pm).
  • UTC is not a time zone, but a time standard that is the basis for civil time and time zones worldwide. This means that no country or territory officially uses UTC as a local time.

I look forward to more feedback on the topic.
