Time of the last quote

Good afternoon. There is a need to get a more accurate time in milliseconds than comes in MarketInfo. Through SymbolInfoTick, it is possible to take time_msc, but there are just seconds multiplied by 1000. From the ideas that came to mind – in OnInit to record the difference between the time of the last quote and GetTickCount() and then use this value. What other options are there? Thank you in advance.
