When stdout is not a TTY, Date#toISOString() is used ...
I hit the problem that when using vcode, set "outputCapture": "std", Date#toISOString() will be used automaticlly instead of showing millisecond diff in vscode debug console(without setting it there will no log at all microsoft/vscode#41600)
So is it possbile to set whether to use Date#toISOString() or not ?
