Copied over from LU-14091:

Note that 0x5f9a449d == 1603945629 and that since the test uses (( ... )) this is not due to a difference of base.

This may be from a final read() done by dd which returns no bytes and does not generate a BRW RPC to the OST. Even though it returns 0 bytes, it requested a non-zero number of bytes and is therefore required to update the file access time.
