TIMESTAMPs should be milliseconds

[malhal]

Just now some of the TIMESTAMPs are created or parsed as seconds with a decimal, they should be converted to milliseconds, i.e. timeIntervalSince1970 + 1000 and rounded. I say, some because I already fixed the one needed for saving a record with a NSDate field.

To find, search for timeIntervalSince1970
