"Host previously down for" is blank

[dulebeograd]

Hi,

I am using Cacti 0.8.8b and Cacti 0.8.8g on Centos 6.5 and 7 respectively.
On both systems I had the same problems with exact information for how long was Host up or down.
I was always getting the info Last Date Checked DOWN : 0000-00-00 00:00:00 Host Previously UP for: 736457d 14h 50m 2s

After I have found the solution for this I get the regular date:
http://bugs.cacti.net/view.php?id=2257

But it only calculates the ammount of time when host was UP and goes down:
Last Date Checked DOWN : 2016-04-06 16:35:02 Host Previously UP for: 20m 1s

It doesnt calculate when host is DOWN and goes UP again:
Last Date Checked UP: 2016-04-06 16:35:02 Host Previously DOWN for:

Hmmmm... had any1 this same problem? And how did you fix it?
