The question for the administrator - in statistics is specified number of a contribution and time of introduction. Payments go each 4 hours why for example on deposits number 20 and 21 there are no payments of percent though time of introduction 15:28 and 15:40, and on deposits with number 14 and 15 percent are already added though introduction time at them later, i.e. 18:20 and 18:21?
