This paper deals with the problem of mobile device time synchronization with millisecond accuracy. We created a solution that will allow synchronizing time on mobile phones depending on accelerometer sensor precision. Our solution is suitable for multiple mobile sensor measurement where the time accuracy of synchronization between mobile phones is needed. We tested the implemented solution on the Android platform.

We observe some results obtained by the author on necessary and sufficient second-order conditions for the strong, bounded strong, Pontryagin's and weak local minimum in optimal control problems with control system, given by ordinary differential equations, considered on a fixed time interval, subject to control constraints and finite number of end-point constraints of equality and inequality type. We assume that the control constraints are given by a finite number of inequalities with linearly independent gradients of active constraints.
