Functions

toIso8601Time()

Converts a DateTimeInterface object to its ISO 8601 time string representation.

toIso8601Time(DateTimeInterface $time) : string

This function generates a normalized ISO 8601 time string from any PHP DateTimeInterface object (DateTime or DateTimeImmutable). The output format is:

  • "THH:MM:SSZ" for UTC (zero offset)
  • "THH:MM:SS±HH:MM" for non-zero offsets

The 'T' prefix separates the time from a potential date component, and the timezone designator can be 'Z' for UTC or a ±HH:MM offset.

Parameters
$time : DateTimeInterface

The time to convert to ISO 8601 format

$dt2 = new DateTimeImmutable('08:15:30', new DateTimeZone('+02:00'));
echo toIso8601Time($dt2); // "T08:15:30+02:00"
