All (most) of the old dates were entered in CST (U.S. Central time zone) as the last day, minute, and second of the month or year in which they were discovered, i.e. time of 23:59:59. When PrimeGrid took it over, all of the times were converted to UTC effectively adding 5 or 6 hours to them.  The dates are now the 1st of the month following the find and the times are all 4:59:59 or 5:59:59 depending on CST daylight saving time at the time of submission. It would be UTC-6 in winter and UTC-5 in summer.
