<script setup lang="ts">import { useDateFormat } from '@vueuse/core'const customMeridiem = (hours: number, minutes: number, isLowercase?: boolean, hasPeriod?: boolean) => {const m = hours > 11 ? (isLowercase ? 'μμ' : 'ΜΜ') : (isLowercase ? 'πμ' : 'ΠΜ')return hasPeriod ? m.split('').reduce((acc, current) => acc += `${current}.`, '') : m
}const am = useDateFormat('2022-01-01 05:05:05', 'hh:mm:ss A', { customMeridiem })
// am.value = '05:05:05 ΠΜ'
const pm = useDateFormat('2022-01-01 17:05:05', 'hh:mm:ss AA', { customMeridiem })
// pm.value = '05:05:05 Μ.Μ.'
