Hello,

I am trying to create a script that writes the date/time to a tag at that scheduled event. Here's what I have but I keep getting "TypeError: expected a str".  
I have tried the destination tagpath as both Date/time and String.

> def onScheduledEvent():  
> rightNow = system.date.now()  
> nowTag = system.tag.readBlocking(['[default]plant/shift/shiftStartTime)'])  
> system.tag.writeBlocking(nowTag,rightNow)

You don't need to read the tag to write to it

```auto
system.tag.writeBlocking(['[default]plant/shift/shiftStartTime)'],[rightNow])

```

`system.tag.readBlocking()` returns a list of `QualifiedValues`.

`system.tag.writeBlocking()` takes a list of tagPaths, and a List of values. As @dkhayes117 has shown.

To get the value read from a tag you need to get it from the list, and then refernece the `value` property of the `QualifiedValue`.

```auto
system.tag.readBlocking(['[default]plant/shift/shiftStartTime'])[0].value

```

For what you're showing here, you don't actually need to read the tag though.

Unless there is some other logic you are wanting to perform.
