LocalTime.fromMillisecondOfDay constructor

LocalTime.fromMillisecondOfDay(
  1. int millisecondOfDay
)

Creates a LocalTime from the number of milliseconds since midnight.

Values are normalized to the range of a 24-hour day (0 to 86,399,999). A value object representing a time of day without any date or timezone information.

LocalTime is immutable and supports operations such as:

  • Parsing from strings
  • Formatting to strings
  • Time arithmetic (addition/subtraction)
  • Comparison and equality checks

This class is useful when working with:

  • Scheduling systems
  • Time pickers
  • Representing specific times (like "08:30 AM") without a date context

Example

final time = LocalTime(14, 30); // 2:30 PM
final later = time.plusMinutes(45); // 3:15 PM
print(later); // 15:15:00

Implementation

factory LocalTime.fromMillisecondOfDay(int millisecondOfDay) {
  final hour = millisecondOfDay ~/ (60 * 60 * 1000);
  final minute = (millisecondOfDay % (60 * 60 * 1000)) ~/ (60 * 1000);
  final second = (millisecondOfDay % (60 * 1000)) ~/ 1000;
  final millisecond = millisecondOfDay % 1000;
  return LocalTime(hour, minute, second, millisecond);
}
