A plugin for day.js that extends the 'format' function, enabling the correct output of abbreviated timezones instead of the standard GMT display.
npm install dayjs-abbr-timezoneThis package is a plugin for day.js that enhances the format function to correctly output abbreviated time zones. This is especially beneficial when the standard z format does not meet your requirements.
For instance, when the timezone is set to Asia/Tokyo, the z format would usually output GMT+9. However, with this plugin, you can use the t format to output JST correctly.
```
npm install dayjs-abbr-timezone
This plugin depends on the utc and timezone plugins of Day.js. Please ensure you've imported and extended them as follows:
`typescript
import dayjs from 'dayjs';
import utc from 'dayjs/plugin/utc';
import timezone from 'dayjs/plugin/timezone';
import abbrTimezone from 'dayjs-abbr-timezone';
dayjs.extend(utc);
dayjs.extend(timezone);
dayjs.extend(abbrTimezone);
`
Then you can use the format function with the t option:
`typescript``
const date = dayjs('2023-01-01T12:00:00Z').tz('Asia/Tokyo');
console.log(date.format('YYYY-MM-DD HH:mm:ss t')); // 2023-01-01 21:00:00 JST
This will correctly display the abbreviated timezone rather than the standard GMT display.
