How to refresh single value datasource in dashboard studio?

[eholz1]

I have a current time query:

| makeresults | eval clock = strftime(now(), "%H:%M:%S")

| eval timestamp = strftime(now(), "%+") | table clock,timestamp

for a single value item on my dashboard. I would like it to be refreshed every second.

I would like this to be a "clock" on my dashboard to display the current time.

How can I do this?

Thanks,
