# V008 The V008 analyzer reports usage of the deprecated [ValidateRFC3339TimeString](https://godoc.org/github.com/hashicorp/terraform-plugin-sdk/helper/validation#ValidateRFC3339TimeString) validation function that should be replaced with [IsRFC3339Time](https://godoc.org/github.com/hashicorp/terraform-plugin-sdk/helper/validation#IsRFC3339Time). ## Flagged Code ```go ValidateFunc: validation.ValidateRFC3339TimeString, ``` ## Passing Code ```go ValidateFunc: validation.IsRFC3339Time, ``` ## Ignoring Reports Singular reports can be ignored by adding the a `//lintignore:V008` Go code comment at the end of the offending line or on the line immediately proceding, e.g. ```go //lintignore:V008 ValidateFunc: validation.ValidateRFC3339TimeString, ```
