Question Nmap icmp timestamp


Hey guys... I'm fairly new to Linux and need some help with Nmap. I'm writing a research paper for school on Nmap and I need to know what each ping function does. (ie icmp ack, icmp syn, icmp timestamp)

I've done a decent job of researching most of them but I'm stuck on the icmp timestamp ping. Can anyone give me a summary of what it does and what it is used for; or direct me to a site that can provide the necessary information. Thanks for your help !! I really appreciate it. :-)

As far as I'm aware icmp timestamp query is used to calculate time a packet takes to reach a destination.

ie.

Source stores the time packet leaves and sends a timestamp request to the destination.

Destination recieves the packet and adds the time it was recieved and the time it was sent back to the original sender.

Sender can then calculate the total round trip time that it took took to reach the destination.

These values can then be used to improve network performance if the time taken is very high.

Paraphrased from my bumper book of "TCP/IP is fun"
