One option here is to override the custom date binder to provide support for multiple date formats. This feature already exists in Grails 2 and 3, but we could add a small customization to provide this until we're done with the Grails 3 migration.

Best way to handle this until we migrate to Grails 3 (0.9.0) would probably to allow longs for timestamps.
