Class DateUtil

java.lang.Object
ubic.gemma.core.util.DateUtil
public class DateUtil extends Object
Date helpers.

Ported in-tree from ubic.basecode.util.DateUtil as part of the Phase 3 baseCode util retirement (see BASECODE_DEP_AUDIT.md). Only the three methods actually used by Gemma have been carried over: convertStringToDate(String, String), getRelativeDate(Date, String), and numberOfSecondsBetweenDates(Collection). Dropped: convertDateToString, getDateTime, getTodayDate, and the dead datePattern static.
