iOS devices adopted the use of Mac absolute time with iOS 5. Mac absolute time is the number of seconds that have elapsed since Mac epoch time, which started at midnight on January 1, 2001. The difference between the Unix epoch time and the Mac time is exactly 978,307,200 seconds. It means you can easily convert the Mac time to the Unix epoch and use the same methods to finally convert it to a human-readable timestamp. Of course, there are a few online converters, such as https://www.epochconverter.com/coredata, as shown in the following screenshot:

Of course, there are offline tools for timestamp conversion as well. We'll introduce you to one of them in the next section.
