Help me translate long value, expressed in hex, back in to a date/time

Question

I have a date value, which I\'m told is 8 bytes, a single \"long\" (aka int64) value, and converted to hex:

60f347d15798c901

How can I convert

Answer 1

I believe you can convert it to a decimal int with hexdec(). That will be a timestap that you can work on with date().
