Date time control types - INTERACTIVE see also U56ON - xs:dateTime, xs:dateTimeStamp and xs:long

 
DATETIME control NOW SUPPORTS dateTimeStamp adding the default timezone
 
Here like in utc inputs whatever value is in [form.timezone] or [form.print.timezone] they are always printed in the default timezone - DATETIME control NOW SUPPORTS dateTimeStamp adding the default timezone
 
When form.timezone='Z' is used, or :form.print.timezone='Z' , the timezone is the configured one: Z, GMT and hour is 8AM, 4 hours before the one printed with +04:00

When form.timezone='default' is used the timezone is the default of JVM, on my server CET
22-dic-2019 9.23 Ora dell'Europa centrale
When form.timezone='inherit' is used the timezone is that of the value, so +04:00
22-dic-2019 12.23 GMT+04:00
for long/utc input whatever value is in [form.timezone] or [form.print.timezone] they are always printed in the default timezone
 
 
 
 
Here use form.print.timezone='Z' to print with timezone GMT
24-giu-2020 9.23 Ora media di Greenwich
Here now prints correctly default timezone
24-giu-2020 11.23 Ora dell'Europa centrale
here inherit works differently because long has no timezone and parsed-from-long calendar seems to be GMT
24-giu-2020 9.23 Ora media di Greenwich
here GMT+04 is used to print, so it will be 4 hours after the GMT formated: h13
