30.6001 shows month days without Jan and Feb. According to the below link, it is calcuated as (365-31-28)/10 = 30.6 but because of a floating point bug, it was used as 30.6001 as a workaround. "30.6001, 25 year old hack?" https://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv011.cgi?read=31650 The value 30.6 is used as i18nutil::monthDaysWithoutJanFeb here instead of 30.6001. The new value is ~30.60000038 which is > 30.6, so the calculations should be correct. In order to make sure, a unit test is added, and part of the values are checked against the values calculated by this website: Julian Day and Civil Date Calculator https://core2.gsfc.nasa.gov/time/julian.html Change-Id: I8cc7e046514dc3de652a1c37399e351cb2b614dc Reviewed-on: https://gerrit.libreoffice.org/c/core/+/125813 Tested-by: Jenkins Reviewed-by: Eike Rathke <erack@redhat.com>
