The default 1 enables time stamping. This option allows the sender to include a
time stamp in every segment. The receiver should acknowledge (or echo) this
stamp so that the sender can use delta for round trip time calculations. Using this
option increases the TCP header from 20 bytes to 32 bytes. Use the no form of the
command to return the ts to the global value. If no global settings exist for a
parameter, the factory default parameter is used instead. See RFC 1323.

The default 1 increases the TCP window from 16 bits to 32 bits. The header size
is not changed, but by enabling the option TCP maintains the windows internally
as a 32-bit value. Having this option enabled can accommodate larger receive
buffers (> 65535) by allowing for significantly larger windows, potentially
increasing the overall efficiency of communications. Use the no form of the
command to return the ts to the global value. If no global settings exist for a
parameter, the factory default parameter is used instead. See RFC 1323.
