How was the problem resolved ?

For int/short just use "htonl/htons" for serialization and "ntohl/ntohs" for 
deserialization. I would NOT try to serialize floating points, that can be a 
real pain. OLSRd use a format defined in the RFC to encode vtimes into a 
single byte value.

Olsrd works with an internal circular time (based on gettimesofday()) measured 
in milliseconds. The scheduler makes sure that the time will only step forward 
and not backward.
