@fendiaoxiaoshuazi Thanks for submitting this issue. Would you mind sharing more details behind this request? Is this about enhancing the existing "offset" mode or would this need to introduce a new mode that mainly displays UTC options a certain way?

fendiaoxiaoshuazi commented 8 months ago

Hi, @jcfranco, we would like an enhancement to the existing "offset" mode. Currently, the "offset" mode can only show "GMT", and we would like an option to switch "GMT +/- " to "UTC +/- ".

Like the time zone picker of Scene Viewer, and Windows time zone picker

fendiaoxiaoshuazi commented 7 months ago

Currently, Survey123 connect and field app use the UTC for the time picker. The web app utilizes the Calcite input-time-zone show GMT. Therefore, we need the UTC mode in the Calcite input-time-zone to make them consistent.

Here are the reasons why we chose UTC:

According to I18N team

The general guideline for all Esri products is to follow UTC, not GMT. So if you display UTC – you’re good and don’t need to change anything.
The timestamp offset field stores data in UTC https://doc.arcgis.com/en/arcgis-online/manage-data/work-with-date-fields.htm#ESRI_SECTION1_A9A8C7B007BE4C898FA84CAED9BCFD89).

Installed and assigned for verification.

geospatialem commented 4 months ago

Verified in 2.10.0-next.10 with the new offset-style attribute (offsetStyle prop) with the following values:

"user" (default)
"gmt" and
"utc"

For example:

<calcite-input-time-zone offset-style="utc"></calcite-input-time-zone>
