| 03:52 | <justingrant> | Note that it's not exactly "tz name is retained" because that would imply that you need to save the actual string the user gave you. Instead, what you need to retain is the case-normalized string ("America/Denver" not "AmerICa/dENver") which allows implementations to store the time zone more efficiently, like as a 10-bit index into a list of supported ID strings. |
