On the following page:
http://api.mongodb.org/java/current/com/mongodb/MongoClientOptions.html
most methods that return time values show the default value.
However some, like the following:

• getMaxConnectionIdleTime
• getMaxConnectionLifeTime
• getHeartbeatFrequency (just putting the default on a separate line should do)
• getMinHeartbeatFrequency (same as above)
• getHeartbeatSocketTimeout (same as above)
• ...
  don't, or are formatted differently.

Note that methods also show Since, but not all of them. Are we consistent with that section?
