failover peer why only for 60 seconds?

[S Kalyanasundaram]

Hi all,
     In the failover setup why are we checking in the peer only for 60 seconds? Subtracting the [cur_time and link->imsg->time] in failover.c can not exceed the 60 seconds. Other wise the peer rejects the connection by saying time offset too large!. May be i am asking a very basic question, but it is not striking.

any help please, 
thanks,
