docs timestamp - Functions - Configuration Language configuration-functions-datetime-timestamp The timestamp function returns a string representation of the current date and time.

timestamp Function

timestamp returns the current date and time.

In the Packer language, timestamps are conventionally represented as strings using RFC 3339 "Date and Time format" syntax, and so timestamp returns a string in this format.

The result of this function will change every second, so using this function directly with resource attributes will cause a diff to be detected on every Packer run.

-> Breaking change note: Packer previously let you decide your own "Date and Time format" syntax. With HCL2 and for parity with Terraform, Packer will be using the RFC 3339 "Date and Time format" syntax. As a string. formatdate still allows you to format a date.
