RFC 3530 says that the seconds value of a nfstime4 structure is a 64bit
value, but we are instead sending a 32-bit 0 and then a 32bit conversion
of the 64bit Linux value. This means that if we try to set atime to a
value before the epoch (touch -t
196001010101) the client will only send
part of the new value due to lost precision.
