# `timestamp` Function
|
|
|
|
`timestamp` returns a UTC timestamp string in [RFC 3339](https://tools.ietf.org/html/rfc3339) format.
|
|
|
|
In the OpenTofu language, timestamps are conventionally represented as
|
|
strings using [RFC 3339](https://tools.ietf.org/html/rfc3339)
|
|
"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
|
|
OpenTofu run. We do not recommend using this function in resource attributes,
|
|
but in rare cases it can be used in conjunction with
|
|
[the `ignore_changes` lifecycle meta-argument](../../language/meta-arguments/lifecycle.mdx#ignore_changes)
|
|
to take the timestamp only on initial creation of the resource. For more stable
|
|
time handling, see the [Time Provider](https://registry.terraform.io/providers/hashicorp/time).
|
|
|
|
Due to the constantly changing return value, the result of this function cannot
|
|
be predicted during OpenTofu's planning phase, and so the timestamp will be
|
|
taken only once the plan is being applied.
|
|
|
|
## Examples
|
|
|
|
```
|
|
> timestamp()
|
|
2018-05-13T07:44:12Z
|
|
```
|
|
|

|
|
* [`formatdate`](../../language/functions/formatdate.mdx) can convert the resulting timestamp to
|
|
other date and time formats.
|
|
* [`plantimestamp`](../../language/functions/plantimestamp.mdx) will return a consistent timestamp
|
|
representing the date and time during the plan.
