[Tinyos-help] How does "time" field work?TOS_Msg

[Munaretto, Daniel]

In AM.h i found TOS_Msg that i'm using. If i display "time " field in my simulations on TinyViz, it's strange, it assumes meaningless values. Does someone know how it works?
 
Thanks for your availability

PS my purpose is to have a statistic about delay, so time when a mote send msg-time when it is received.
