The reconnect timer can be adjusted in 1.0.31?

Hi, 

When the meta connection get lost, it’ll be reconnect like below:
Trying to re-establish outgoing connection in 5 seconds, and if it’s failed, then the timer will be increased for another try.

My question is, how to adjust the reconnect timer, in some cases, the reconnect delay for a while(increase to something longer) will be beneficial for the unstable connection.
