Grails saves datetime as UTC time, but reads it as local server time

Grails saves datetime as UTC time, but reads it as local server time???

The timestamp is read back as local time instead. So if my timezone is +2 UTC and the current local time is 12:30:00, what will be saved to the database is 10:30:00, but when I read it back, it becomes 10:30:00. Does anybody know how to fix this problem so that Grails will read the timestamp back as UTC and convert it accordingly?

I have the following line in my Grails application (BootStrap.groovy) to set the default timezone to UTC:

TimeZone.setDefault(TimeZone.getTimeZone("UTC"))

And above line solved my problem. Now I can set time anything to db and returned back the same date to my domain field

Php determine if date string is a valid date in that format

Code snippet

function validateDate($date_string)
{
    $date_value = DateTime::createFromFormat('Y-m-d', $date_string);
    return $date_value && $date_value->format('Y-m-d') === $date_string;
}

Some examples

var_dump( validateDate('2016-13-10'));   // false
var_dump( validateDate('20160-13-10'));  // false
var_dump( validateDate('2016-11-32'));   // false
var_dump( validateDate('2017-02-29'));   // false

var_dump( validateDate('2016-11-02'));   // true
var_dump( validateDate('1970-12-21'));   // true
var_dump( validateDate('2017-07-29'));   // true

Get day diferrence between two dates using JAVA

return (int)( (date2.getTime() - date.getTime()) / (1000 * 60 * 60 * 24));

First day of next month with java Time

public static Date getNextMonth() {
    Date current = new Date();
    Calendar c = Calendar.getInstance();
    c.setTime(current);
    c.add(Calendar.MONTH, 1);
    c.set(Calendar.DATE, 1);

    c.set(Calendar.HOUR, 0);
    c.set(Calendar.MINUTE, 0);
    c.set(Calendar.SECOND, 0);
    return c.getTime();
}

Date nextMonth = getNextMonth();
System.out.println(nextMonth);

And output as if you check it withing november month.
