In hex, that’s 7E420A which doesn’t immediatley look helpful.
But hex 7E4 is decimal year 2020 …
hex 2 is month 2, Feb (Dec would be hex C)
hex 0A is decimal day 10
2020 Feb 10
It’s messed up BCD
Conversion rule -
convert to hex
Leading three characters for binary year
next character for binary month
next two characters for binary day
