An utility to format current datetime as a UTC string according to RFC 3339

A procedure to use in Seeburger BIC Mapping Designer
It will extend your library for string handling

• Get current date / time with time zone (system default)
• Format output

// -----------------------------

// -----------------------------
// procedure getCurrentDateTimeUTC
// Parameters: None
//     Get current date / time
//     Format as String in UTC RFC 3339 format (eg 2022-10-13T23:37:18+02:00)
// Output
//    alphanumeric / String

#importJavaStart
    import java.time.format.DateTimeFormatter;
    import java.time.OffsetDateTime;
#importJavaEnd

local output$;

#javaStart
    String output;

    DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ssXXX");
    OffsetDateTime now = OffsetDateTime.now();
    output = dtf.format(now);

    _StrVar_OUTPUT.setString(output);
#javaEnd

exitProc(output$);

Same but with inout parameters

• Concatenate parameters
• Parse string
• Add system default time zone
• Format output
