๐ŸŽฏ High Precision Timestamp

Tips

It may be used to generate order numbers or to interface with other programming languages

Millisecond, microsecond, and nanosecond methods return Unix timestamps in different units. Calculations use integer string concatenation to avoid losing low-order digits through floating-point arithmetic.

The underlying microtime() provides microsecond precision. Nanosecond values are microsecond values multiplied by 1000, so their last three digits are zero; this does not provide nanosecond measurement precision. Millisecond values are truncated rather than rounded up.

If a result exceeds the platform's PHP_INT_MAX, the method throws OverflowException. A 64-bit PHP runtime is recommended.

getTimestamp()

To obtain a timestamp in seconds, you can use the system function time() instead

Parameters

noting

Return Values

Timestamp in the current seconds

Example code

/* Gets the timestamp of the current second */
TimeHelper::getTimestamp();
// 1698762509

getMilliTimestamp()

Get millisecond timestamps

Parameters

noting

Return Values

The timestamp of the current millisecond level

Example code

/* Obtain the timestamp of the current millisecond */
TimeHelper::getMilliTimestamp();
// 1698762509279

getMicroTimestamp()

Get microsecond timestamps

Parameters

noting

Return Values

The current microsecond timestamp

Example code

/* Get the current microsecond timestamp */
TimeHelper::getMicroTimestamp();
// 1698762509279645

getNanoTimestamp()

Get nanosecond timestamps

Parameters

noting

Return Values

The current Unix timestamp in nanosecond units, with microsecond precision

Example code

/* Obtain the current nanosecond timestamp */
TimeHelper::getNanoTimestamp();
// 1698762509279645000
