How to reset value of the timer

Hi
      I have added
ADD_ANALYZER_TIMER(&TCP_Analyzer::AckTimer1,tcp_ACK_timeout,0,TIMER_TCP_EXPI
RE); in TCP.cc file. AckTimer1 is my own function which executes when ACK
doesn't comes within tcp_ACK_timeout (This sets to 6.5 sec). I want to
reset the value of tcp_ACK_timeout when Acknowledgment comes. Can you
give me solution for this?

Bye

Generally you can't change the value of an existing timer. You need
to cancel the previous one and the install a new one with the
modified expire time.
