 * Durations that must stay positive whole numbers after Carbon 3.
 *
 * Carbon 3 made diffIn*() signed and fractional: now()->diffInMinutes($past) became negative. Unchanged,
 * that silently disabled the inactivity logout, presence updates and the processing of inactive profiles,
 * and put negative periods in the warning mails. The code now passes absolute = true and casts to int,
