For instance, the following data value represents the current day in UTC:
Timestamp +2018-05-17T00:00:00Z
Timezone +00:00
Calendar Gregorian
Precision 1 day
Before 0
After 1
(meaning that it starts at the beginning of 2018-05-17, midnight, and continues until the next day)
When creating a claim with a date value in the Wikibase UI, by default the "After" parameter is set to 0 (see [[ https://www.wikidata.org/w/index.php?title=Q4115189=prev=680600484 |this example]]). Is it intentional? I believe that 1 should be the default value there (regardless of the precision).
If this is indeed a bug, should we run a bot to fix all the date values?
If this is not a bug, then there is a bug in Wikidata-Toolkit, which agrees with my interpretation of the default value:

(except that there is a typo there: before-tolerance should obviously be after-tolerance in the last comment)TASK DETAILhttps://phabricator.wikimedia.org/T194869EMAIL PREFERENCEShttps://phabricator.wikimedia.org/settings/panel/emailpreferences/To: CommunityTechBotCc: Tpt, Pintoch, AndyTan, Zylc, 1978Gage2001, Lahi, Gq86, herron, GoranSMilovanovic, Chicocvenancio, alanajjar, QZanden, Tbscho, LawExplorer, Lea_WMDE, Mattias_Ostmar-WMSE, JJMC89, Jseddon, Ryuch, Mkdw, RuyP, JEumerus, Trizek-WMF, KasiaWMDE, 0x010C, srodlund, Luke081515, grin, Bsadowski1, mys_721tx, Wikidata-bugs, Snowolf, aude, Huji, Gryllida, jayvdb, Tobi_WMDE_SW, revi, scfc, He7d3r, Romaine, Mbch331, Jay8g, Glaisher, Krenair, chasemp___
