I found the kotlinx-date-time tag. That tag represents the library kotlinx-datetime.
Notice the difference in spelling. The tag was incorrectly named with a second hyphen. The tag should be kotlinx-datetime.
According to this meta page, the way to rename a tag is to post here.
6/6 questions have been retagged; kotlinx-date-time no longer exists. kotlinx-datetime is now appropriately named:
