# 简介

Roll Bot supports different time zones and languages.

## Timezone

Roll Bot uses [offset](https://en.wikipedia.org/wiki/UTC_offset) to record time zones, and utilizes it when parsing and sending times.

Since the offset is a fixed value, users using daylight time may need to adjust their offsets several times.

## Language preferences

Roll Bot uses [IETF language tag](https://en.wikipedia.org/wiki/IETF_language_tag) to record language preferences, and uses it when sending content.

Language currently supported by Roll Bot includes `en-US` `de-DE`
