These representations of time are mainly for internal use.

If an end user interaction with dates and times is required, the software will nearly always convert this internal number into a date and time representation that is comprehensible to humans.

Time measurement units are counted from the epoch so that the date and time of events can be specified unambiguously.

Events taking place before the epoch can be dated by counting negatively from the epoch, though in pragmatic periodization practice, epochs are defined for the past, and another epoch is used to start the next era, therefore serving as the ending of the older preceding era.

Most famously, older systems which counted time as the number of years elapsed since the epoch of January 1, 1900 and which only allotted enough space to store the numbers 0 through 99, experienced the Year 2000 problem.

Many Unix-like operating systems which keep time as seconds elapsed from the epoch date of January 1, 1970, and allot timekeeping enough storage to store numbers as large as will experience an overflow problem on January 19, 2038 if not fixed beforehand. A correction involving doubling the storage allocated to timekeeping on these systems will allow them to represent dates more than 290 billion years into the future.The whole purpose and criteria of such definitions are to clarify and co-ordinate scholarship about a period, at times, across disciplines.Epochs are generally chosen to be convenient or significant by a consensus of the time scale's initial users, or by authoritarian fiat.In the fields of chronology and periodization, an epoch is an instant in time chosen as the origin of a particular era.The "epoch" then serves as a reference point from which time is measured.
