#' Derive time of culling
#'
#' Function to devide the time of culling for all individuals
#' @param population Population list
#' @param database Groups of individuals to consider for the export
#' @param gen Quick-insert for database (vector of all generations to export)
#' @param cohorts Quick-insert for database (vector of names of cohorts to export)
#' @param use.id Set to TRUE to use MoBPS ids instead of Sex_Nr_Gen based names (default: FALSE)
#' @examples
#' data(ex_pop)
#' get.cullingtime(ex_pop, gen=2)
#' @return Time of death of in gen/database/cohorts selected individuals
