PT2M45S

PT2M45S is a representation of a duration in ISO 8601 format. The notation follows the standard for composite time periods, where "P" indicates a period, "T" separates the date and time components, and the letters that follow represent specific units. In this instance, "2M" denotes two minutes and "45S" denotes forty‑five seconds, so the entire string describes a period of 2 minutes and 45 seconds.

This format is widely used in computing and data exchange, especially in contexts where precise temporal spans must be conveyed in a language‑agnostic manner. Examples include specifying timeouts and delays in XML, scheduling events in calendar applications, and defining durations in media metadata such as video and audio files. Because the string is purely textual, it can be parsed and validated with standard libraries that support ISO 8601 durations across many programming languages.

To convert PT2M45S to other units, add the minutes and seconds together: two minutes are 120 seconds, plus 45 seconds equals 165 seconds. In hours, that is approximately 0.04583 hours. When writing human‑readable durations, one might express it as "2 minutes 45 seconds" or simply "165 seconds."

The specification for ISO 8601 allows optional year, month, week, day, hour, minute, and second elements. The omission of the date portion (years, months, days) and the inclusion of only time components, as in PT2M45S, indicates that the duration is purely temporal and not bound to a calendar date.
