Question

When combining data from four data sources, you notice that timestamp data about transactions are represented differently in each of the data sources. The timestamp for one transaction is presented in each source respectively as follows: "Fri, 21 Jan 2022 00:02:09 UTC", "Friday, January 21, 2022 07:02:09 AM", "1642748529", "44582.2931597222". The first source uses UTC, the second uses the local timezone, the third uses the Epoch timestamp, and the fourth uses the Excel timestamp. All represent that same exact time. How would you determine which timestamp to output in your transformation?

	a	Refer to the data requirements
	b	Use the Excel variant as it is the most universal
	c	Output all four variants
	d	Use the UCT variant as it is not sensitive to time zone
	e	Use the Epoch variant as it is common in programming
