Hello Experts, 

while launching my application to Zapier market place, i am getting this warnings on all my zap triggers, Looking for someone who can help 

Here are the details: 

ISO-8601 Date/Time Format in Zap History

To ensure Zapier can correctly parse dates and times, you should always use ISO-8601 format to represent dates or times. Timezone info should also be present if it contains time.

Unlike D023, this check validates the data in the Zap History instead of static samples.

Just wanted to circle back in here to share our Support Team’s suggestion to @maro_integrations in case it’s helpful to anyone that may be running into a similar date format warning:

“To resolve this, you'll need to update the code for the trigger so that the date fields are returned in ISO-8601 format.
