When I try to get the last time that I contacted some contacts, the results has the value converted to "01/01/1970" but I know the real date and time of the last call (for example, it is 14/02/2016). I noted that in my logs the last saved call is that was at one and half year ago, but the call I try to find was in 2 years ago.

So, am I correct in understanding that after some long time the log loses the older calls and in the contacts2.db the last\_time\_contacted field updates to incorrect values?
