Rangeselector for time: hour, minute, second

Hello,

I found this rangeselector-example for year, month and day - but I need the equivalent for hour, minute and second.
Can anybody help me?

Thanks

michael

Add range slider

fig.update_layout(
xaxis=dict(
rangeselector=dict(
buttons=list([
dict(count=1,
label=“1m”,
step=“month”,
stepmode=“backward”),
dict(count=6,
label=“6m”,
step=“month”,
stepmode=“backward”),
dict(count=1,
label=“YTD”,
step=“year”,
stepmode=“todate”),
dict(count=1,
label=“1y”,
step=“year”,
stepmode=“backward”),
dict(step=“all”)
])
),
rangeslider=dict(
visible=True
),
type=“date”
)
)
