Datetime.conf

‘’‘In Progress’‘’

The output, or display, of dates and times inside dateRange metadata elements can be configured in datetime.conf. For valid <em>input</em> formats for dates and times, please visit [[Date_and_Time_Formats|this page.]]

Date/time output configuration

In Datetime.conf, you may define common text expressions you wish to have the date/time parser convert to dates. The text expression on the left side of the equal sign must be all lowercase; the date/time expression on the right side must be valid and parsable:

expressions = {
   us civil war = 1861 to 1865,
       world war 2  = 1939 to 1945,
   nickel empire = 1920s,
}
