void net_timeout_set (struct net_timeout *timeout, uint32_t lifetime, uint32_t now)
 Configure a network timeout structure.
int64_t net_timeout_deadline (const struct net_timeout *timeout, int64_t now)
 Return the 64-bit system time at which the timeout will complete.
uint32_t net_timeout_remaining (const struct net_timeout *timeout, uint32_t now)
 Calculate the remaining time to the timeout in whole seconds.
uint32_t net_timeout_evaluate (struct net_timeout *timeout, uint32_t now)
 Update state to reflect elapsed time and get new delay.

Timer that runs longer than about 49 days needs to calculate wraps.
