When working with data from different sources, one may encounter a various number of different date formats.

Examples include:

  • yyyy-MM-dd hh:mm:ss
  • yyyy-MM-dd hh:mm:ss.zzz
  • yyyy-MM-dd hh:mm:ss.zzzzzz (not even supported with format strings)
  • yyyy/MM/dd hh:mm:ss
  • yyyy/MM/dd hh:mm:ss.zzz
  • yyyy/MM/dd hh:mm:ss.zzzzzz (not even supported with format strings)

These are all supported by Qt's Qt::ISODateWithMs, which thus allows for instantly loading different csv's without having to adjust the date format every time. This pull request adds a user-selectable UI option to parse dates as ISO8601.

The new UI suggested for that looks like this:

New 'parse CSV' UI, with radio button ISO 8601 unchecked New 'parse CSV' UI, with radio button ISO 8601 checked

ISO 8601 parsing is highly flexible. This allows to load data of different origin using different date formats subsequently, without having to adjust the date format string every time when switching back and forth.
