It should be,

t_1, the origin timestamp, is the time according to the client at
which the request was sent.
t_2, the receive timestamp, is the time according to the server at
which the request was received.
t_3, the transmit timestamp, is the time according to the server at
which the reply was sent.
t_4, the destination timestamp, is the time according to the client at
which the reply was received.

The reference timestamp isn't really used for anything, and the
destination timestamp obviously can't be part of the packet.
