Time format in moderation interfaces Some moderation interfaces, for example the ban duration when moderating posts, or the ban duration for post filtering use a shorthand for times/length. This format supports years, months, weeks, days, hours, minutes and seconds.
An input of "3mo" would mean 3 months and "1y2mo3w4d5h6m7s" would mean 1 year, 2 months, 3 weeks, 4 days, 5 hours, 6 minutes and 7 seconds.
