How to draw shapes with a future timestamp in the Tradingview api?

[sangdx]

I want to draw shape with IChartWidgetApi, first vertical line with timestamp now and second verify line but both of them is same position.
#first vertical line
chart().createShape(
{ time: new Date().getTime() / 1000 },
{shape: 'vertical_line'}
);
#second vertical line
chart().createShape(
{ time: new Date().getTime() / 1000 + 60 },
{shape: 'vertical_line'}
);
Is there any other way to create a vertical line that can achieve my wishes, or if I do the above, how can I fix it?
