A date can usually be identified as a place-holder if the date falls on the 1st of the month and the time is 4:59:59 or 5:59:59. All/most of the old dates/times were entered in CST (U.S. Central time zone) as the last day, minute, and second of the month/year in which they were discovered, i.e. local time of 23:59:59. When PrimeGrid took over management of the site, all of the times were converted to UTC. This had the effect of adding 5 or 6 hours to them depending on CST daylight saving time on the date of the original submission resulting in all dates shown now as the 1st of the month.

===Times===

* All times shall be based on a 24-hour clock (<code>HH:MM[:SS]</code>).

* There is no consensus yet as to a standard time zone for this Wiki.
