Golang-inspired time helpers for PHP 8.2+.

Installation

composer require dcarbone/gotime

Quick start

<?php

use DCarbone\Go\Time;

$t = Time::Now();
$d = Time::ParseDuration('1h30m');

echo $t, PHP_EOL;              // formatted timestamp
echo $d, PHP_EOL;              // 1h30m0s
echo $d->Nanoseconds(), PHP_EOL; // 5400000000000

API overview

This package exposes a static facade class, DCarbone\Go\Time, plus several value objects under DCarbone\Go\Time\*.

Duration (DCarbone\Go\Time\Duration)

Duration stores elapsed time as a signed integer count of nanoseconds.

Common construction patterns:

use DCarbone\Go\Time;

$a = new Time\Duration(5 * Time::Second);
$b = Time::ParseDuration('5s');
$c = Time::Duration('1h2m3.5s'); // cast helper

Supported ParseDuration() units:

• ns
• us, µs, μs
• ms
• s
• m
• h

Key methods:

• Nanoseconds(), Microseconds(), Milliseconds(), Seconds(), Minutes(), Hours()
• Truncate(Duration $m), Round(Duration $m)
• Compare(Duration $other) (-1, 0, 1)
• DateInterval() / IntervalSpec()
• __toString() (Go-like formatting, e.g. 500ms, 1h2m3.004s)
• jsonSerialize() (raw nanosecond integer)

Time (DCarbone\Go\Time\Time)

Time\Time extends \DateTime and adds Go-style helpers.

Primary constructors:

use DCarbone\Go\Time;

$zero = Time::New(); // Unix epoch
$now  = Time::Now(); // current time

Comparison helpers:

• Before(Time $t), After(Time $t), Equal(Time $t)
• BeforeDateTime(\DateTimeInterface $dt), AfterDateTime(...), EqualDateTime(...)

Unix helpers:

• Unix()
• UnixNano()
• UnixNanoDuration()

Date/time part helpers:

• Year(), Month(), Day(), Weekday()
• Hour(), Minute(), Second(), Nanosecond()
• IsZero()

Duration arithmetic:

• AddDuration(Duration $d)
• SubDuration(Duration $d)

Static facade helpers (DCarbone\Go\Time)

• Constants: Nanosecond, Microsecond, Millisecond, Second, Minute, Hour
• Constructors and now/epoch:
  • New()
  • Now()
• Duration operations:
  • ParseDuration(string $s)
  • Duration(null|string|int|float|Duration|\DateInterval $input)
  • CompareDuration(Duration $d1, Duration $d2)
  • ZeroDuration()
• Relative time:
  • Since(Time\Time $t)
  • SinceDateTime(\DateTimeInterface $dt)
  • Until(Time\Time $t)
  • UntilDateTime(\DateTimeInterface $dt)

Supporting value types

• Time\Month (month ordinal/name helpers)
• Time\Weekday (weekday ordinal/name helpers)
• Time\IntervalSpec (intermediate duration-to-interval representation)
• Time\DateInterval (extends \DateInterval, including fractional seconds support)

Notes

• Precision in PHP runtime is microseconds; nanosecond APIs are represented as integer nanoseconds derived from microsecond resolution.
• Duration(\DateInterval $input) converts years/months using average-hour constants, so calendar-month/year conversion is approximate.
