bp_core_time_since( int|string $older_date, int|bool $newer_date = false )

Get an English-language representation of the time elapsed since a given date.

Description

Based on function created by Dunstan Orchard – http://1976design.com

This function will return an English representation of the time elapsed since a given date. eg: 2 hours and 50 minutes eg: 4 days eg: 4 weeks and 6 days

Note that fractions of minutes are not represented in the return string. So an interval of 3 minutes will be represented by "3 minutes ago", as will an interval of 3 minutes 59 seconds.

Parameters

$older_date

(Required) The earlier time from which you're calculating the time elapsed. Enter either as an integer Unix timestamp, or as a date string of the format 'Y-m-d h:i:s'.

$newer_date

(Optional) Unix timestamp of date to compare older date to. Default: false (current time).

Default value: false

Return

(string) String representing the time since the older date, eg "2 hours and 50 minutes".
