Hi!

Does `now(-1)` stop it's execution so only updates on start?

I have a date selector with it's `minDate` property set to this:

```python
midnight(
	addMonths(now(60),-1)
)

```

If I set the pollrate to -1 does it only update at the start of the view or I have to set a custom property to set the start value that is set onStart?

Hi,

See the documentation:

> **[now | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/appendix/expression-functions/date-and-time/now)**
>
> Returns the current time.

In the description, it says "If you do not specify a pollRate, it will default to 1,000ms. If you do not want this function to poll, use a poll rate of zero."

So `now(0)` is the way to go.
