Extra background on dates from a software angle!

Dates seem simple at first, but making dates robust can quickly run into multiple issues:

  • Which calendar system?
  • Which date general format? e.g. dd/mm/yyyy (UK), mm/dd/yyyy (USA), yyyy-mm-dd (some computer systems)
  • Which specific date format i.e. with leading zero's (01) or without leading zero (1)
  • Where is the date going to be used, logging, presentation data
  • Millemium bug... systems that only store two digits for the year data!

This all gets more complex and potential for error when you add in the concept of time with a date.

  • Is timezone important now or possibly in the future?
  • Is the data recorded with the timezone declared or associated.
  • Is the data recorded all in the same timezone, if it isn't declared? (it happens even just with UK data as systems operate in BST and GMT at times)
  • Ideally recording time in UTC for constitant data is a good start.
  • Having geo lat,long or similar data to localise time as experienced.
