I’m playing around with the v4 API to retrieve contributions made between two points in time. However, I’m running into an issue know that makes we question the implementation of the filterting on the API.
I’m using the from and to parameters on https://developer.github.com/v4/object/user#contributionscollection.
The documentation about the DateTime scalar tells me that a DateTime is An ISO-8601 encoded UTC date string. which would mean 2019-01-01 (date only) however the API tells me that this is invalid so I’m using a ISO Extended Z string like 2019-01-01T00:00:00Z which works.
There is only one issue. It looks like the filter only looks at the date component and not at the time.
This is problematic since I’m passing in datetime values in UTC (Z) that have been converted from local timezone (GMT+1).
This means that If I wanna list all contributions at the day of 2019-01-01 it will get turned into 2018-12-31T23:00:00Z since only the date is respected this will also return all entries that happened at the 2 018-12-31.
This feels broken to me since the API should accept a date string without the time information if only this is used.
