Displaying local time

What is the best way to display time-series in local (browser) time zone?

If I am sending data with time zone - it is always converted to UTC.

Without time zone it is displayed as is…

(The only option I though of is converting the time on server and sending it without time zone - but proper solution is always to use browser time zone somehow)

Thanks

Hi,

The best option is probably a FuncTickFormatter or Custom extension formatter that has a little JS code to format the ticks according to your needs.

Thanks,

Bryan

Thanks Bryan,

The following works fine:

fig.xaxis.formatter = FuncTickFormatter(code = """

    date = new Date(tick);
    return date.toLocaleDateString('en-EN', {
      hour: '2-digit',
      minute: '2-digit',
      hour12: false,
      month: 'short',
      day: 'numeric'
    }).replace(',', '');
""")
