The parseTimestampToDate function is duplicated in both src/Shared/utils.ts and src/Pages-Devtron-2.0/Shared/utils.ts. This creates code duplication and maintenance overhead. Consider keeping the function in only one location (preferably src/Shared/utils.ts as it's more general) and importing it from there when needed in Pages-Devtron-2.0.

Suggested change

	export const parseTimestampToDate = (timestamp: string): string => {
	const dateObj = dayjs(timestamp)
	return dateObj.format(DATE_TIME_FORMATS.DD_MMM)
	}
	import { parseTimestampToDate } from '../../../Shared/utils'
