This sounds like a Java question rather than a Grails question - you might find it helpful to look at the Java Data Time classes: https://docs.oracle.com/javase/tutorial/datetime/TOC.html

It looks as though the REST API is returning dates in ISO 8601 format, which is a universal and unambiguous way of representing dates and times - you need to convert an ISO 8601 string into a date and time string formatted according to the local conventions, which vary betweem countries: https://en.wikipedia.org/wiki/ISO_8601

You basically need to use a

java.time.format.DateFormatter

object to convert what looks like an ISO_INSTANT date and time into something more readable such as an RFC_1123_DATE_TIME: https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html

I solved adding

Copy code

implementation "org.codehaus.groovy:groovy-dateutils:3.0.19"

Into build.gradle and modify my gson view like:

Copy code

json {
    date mydate.format('dd-MM-yy HH:mm')
}

And works fine

The

groovy-dateutil

module is based on Java's legacy Date and Calendar types - it might better to use the

groovy-datetime module

, which supports working with the new Date/Time API https://groovy-lang.org/groovy-dev-kit.html#_working_with_datetime_types

This version is not compatible with groovy 3 and grails 5, maybe it will be compatible with grails 6
