Dates and Times in EVA Netmodeler
The Archi Date data type
EVA Netmodeler stores dates in the form of a four digit year, two digit month and two digit date. Dates are normally displayed in the form:
CCYY/MM/DD e.g. 2005/08/12 for the 12th August 2005.
When a date is entered, you can use a variety of formats:
- You may enter years as two digits or four digits
- You can enter months in full e.g. August
OR in abbreviated form e.g. Mar
OR as one or two digits
- You can use other separators than those chosen for display
e.g. 2005-1-20
EVA Netmodeler validates dates upon entry. If a date is not entered or is invalid, it will be stored and interpreted as UNKNOWN. This is important - you will not be forced to enter a "valid" date when it is unknown (e.g. the
finish date for a project when you are busy setting up the initial plan). It is sometimes more accurate to have an UNKNOWN date value. EVA Netmodeler will handle these correctly in calculations too - if any calculation using a
date as a source value finds an UNKNOWN value, the result will also be UNKNOWN.The Calendar Browser has a feature to display items where the start or end dates are UNKNOWN, so that these can be easily located for updating when
information becomes available.
