The use of the ``++ZonedDateTime++`` class introduced in Java 8 to truncate a date can be significantly faster than the ``++DateUtils++`` class from Commons Lang.
*Note* that this rule is automatically disabled when the project's ``++sonar.java.source++`` is lower than ``++8++``.
== Noncompliant Code Example
----
public Date trunc(Date date) {
return DateUtils.truncate(date, Calendar.SECOND); // Noncompliant
}
----
== Compliant Solution
----
public Date trunc(Date date) {
Instant instant = date.toInstant();
ZonedDateTime zonedDateTime = instant.atZone(ZoneId.systemDefault());
ZonedDateTime truncatedZonedDateTime = zonedDateTime.truncatedTo(ChronoUnit.SECONDS);
Instant truncatedInstant = truncatedZonedDateTime.toInstant();
return Date.from(truncatedInstant);
}
