How do you find the difference between two timestamps?

If you’d like to calculate the difference between the timestamps in seconds, multiply the decimal difference in days by the number of seconds in a day, which equals 24 * 60 * 60 = 86400 , or the product of the number of hours in a day, the number of minutes in an hour, and the number of seconds in a minute.
