How to Convert currentTimeMillis to a Date with Locale-Specific Formatting

Problem:

When converting milliseconds to a date format using SimpleDateFormat, the program uses the date of the machine, which may not represent the correct time in a different time zone.

Solution:

To handle this issue elegantly, you can use the following approaches:

• Java.util.Date:

<code class="java">Date date = new Date(millis);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss,SSS", Locale.US);
String formattedDate = sdf.format(date);</code>

• Java Time API (Java 8 ):

Using Instant and ZonedDateTime:

<code class="java">Instant instant = Instant.ofEpochMilli(millis);
ZonedDateTime zonedDateTime = ZonedDateTime.ofInstant(instant, ZoneId.of("US/Central"));

// Format the date
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss,SSS");
String formattedDate = zonedDateTime.format(formatter);</code>

Using LocalDateTime:

<code class="java">LocalDateTime localDateTime = LocalDateTime.ofInstant(instant, ZoneId.of("US/Central"));

// Format the date
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss,SSS");
String formattedDate = localDateTime.format(formatter);</code>

• Joda-Time (legacy)

<code class="java">DateTime jodaTime = new DateTime(millis, DateTimeZone.forTimeZone(TimeZone.getTimeZone("US/Central")));

// Format the date
DateTimeFormatter parser1 = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss,SSS");
String formattedDate = parser1.print(jodaTime);</code>

By using these approaches, you can convert milliseconds to a date format in a locale-specific manner, ensuring that the correct time is represented.
