Endianness with of 8 octets?

[PolynomialDivision]

I'm struggling with Beacon-Reports.
There is a field called Actual Measurement Start Time consisting of 8 octets.
utils.h of libubox gives me the ability to convert endianness, but only up to 64 bit?

I´m a bit confused...

... 8 octets.
..., but only up to 64 bit?

One Octet is one Byte, right?

8 x 8 = 64 Bits

Where is the problem?

Whups. You are right.
