epoch.rfc1123() --- same as Date.toUTCString()
epoch.rfc2822() --- same as Date.toUTCString()
epoch.iso8601() --- YYYY-MM-DD[T]hh:mm:ss[+0000]
epoch.sqldate() --- YYYY-MM-DD
epoch.sqltime() --- hh:mm:ss
epoch.sqlsod() --- start of day, YYYY-MM-DD [00:00:00]
epoch.sqleod() --- end of day, YYYY-MM-DD [23:59:59]
epoch.datetime() --- YYYY-MM-DD hh:mm:ss
epoch.ordinal() --- pass in any number and get back the number + ordinal suffix
For all methods listed here, if the method is called with no argument, the current value of that date fragment is returned. If a value is supplied, the internal Date object is updated and the updated date fragment returned. These methods are wrappers for their native equivalents of a similar name.
- 5 or "9", integer or stringified integer - sets value
- "-2" or "+4" - adds or subtracts from existing value
