Ability to Choose: Timestamp of Bars based on "Open" or "Close" of bar

Issue:
It is currently understood the MC's chart timestamp is based on "Close" of bar.

It means that the bar that is open, for example, at 15:58 and closed at 15:59, will acquire the 15:59 time.
This is hard coded and cannot be changed.

However many other platforms (i.e. Thinkorswim, TradingViews) uses "open" of bar for their timestamp.

This difference of timestamp setup will result significant chart difference, especially with larger and larger intraday time intervals (i.e. 30min, 1h, 4h, 8h). And due to significant chart difference between other platforms, the indicators/signals/strategies will result very differently.

Feature Request:
An option to let MC user to select to use either "Open" or "Close" of bar for chart timestamp at program level will be very beneficial. If use decided to change from "Close" to "Open", entire MC programs must be shutdown and than restarted for it to take effect.
