小程序修改手机时区后，wxgetWeRunData返回的每日记录里step都为0

如何看待微信公开课小程序热门讨论「小程序修改手机时区后，wxgetWeRunData返回的每日记录里step都为0」
摘要：小程序修改手机时区后，wxgetWeRunData返回的每日记录里step都为0
展开：重现步骤：1、小程序wx.getWeRunData返回的每日步数值原本正常；2、修改手机的时区为渥太华或东京等其他国家的时区；3、杀掉手机微信进程；4、重新进入小程序，wx.getWeRunData返回的每日步数值都为0；注：若第4步返回的步数仍为正确值，则刷新多几次，之后就一直返回步数为0；我使用的是iphone6ios11.0.3测试。北京时区数据：[{timestamp:1506182400,step:13932},{timestamp:1506268800,step:9521},{timestamp:1506355200,step:7169},{timestamp:1506441600,step:11387},{timestamp:1506528000,step:5634},{timestamp:1506614400,step:8841},{timestamp:1506700800,step:14228},{timestamp:1506787200,step:11909},{timestamp:1506873600,step:28139},{timestamp:1506960000,step:8680},{timestamp:1507046400,step:13433},{timestamp:1507132800,step:9888},{timestamp:1507219200,step:12955},{timestamp:1507305600,step:12012},{timestamp:1507392000,step:11224},{timestamp:1507478400,step:11896},{timestamp:1507564800,step:10343},{timestamp:1507651200,step:14666},{timestamp:1507737600,step:15013},{timestamp:1507824000,step:12252},{timestamp:1507910400,step:16232},{timestamp:1507996800,step:6333},{timestamp:1508083200,step:9456},{timestamp:1508169600,step:10034},{timestamp:1508256000,step:11031},{timestamp:1508342400,step:15881},{timestamp:1508428800,step:10467},{timestamp:1508515200,step:14077},{timestamp:1508601600,step:18569},{timestamp:1508688000,step:10674},{timestamp:1508774400,step:10384}]渥太华时区数据：[{timestamp:1506182400,step:0},{timestamp:1506268800,step:0},{timestamp:1506355200,step:0},{timestamp:1506441600,step:0},{timestamp:1506528000,step:0},{timestamp:1506614400,step:0},{timestamp:1506700800,step:0},{timestamp:1506787200,step:0},{timestamp:1506873600,step:0},{timestamp:1506960000,step:0},{timestamp:1507046400,step:0},{timestamp:1507132800,step:0},{timestamp:1507219200,step:0},{timestamp:1507305600,step:0},{timestamp:1507392000,step:0},{timestamp:1507478400,step:0},{timestamp:1507564800,step:0},{timestamp:1507651200,step:0},{timestamp:1507737600,step:0},{timestamp:1507824000,step:0},{timestamp:1507910400,step:0},{timestamp:1507996800,step:0},{timestamp:1508083200,step:0},{timestamp:1508169600,step:0},{timestamp:1508256000,step:0},{timestamp:1508342400,step:0},{timestamp:1508428800,step:0},{timestamp:1508515200,step:0},{timestamp:1508601600,step:0},{timestamp:1508688000,step:0},{timestamp:1508774400,step:0}]了解更多
