Commit like you're in Burkina Faso, Gambia, Ghana, Greenland, Guinea, Guinea-Bissau, Iceland, Ireland, Ivory Coast, Liberia, Mali, Mauritania, Morocco, São Tomé and Príncipe, Senegal, Sierra Leone, Togo, the United Kingdom or part of Antarctica.
Git leaks timezone information via AuthorDate and CommitDate, which could reveal your location.
Link post-commit to $GIT_DIR/hooks/. This will change the timezone attached to the commit, putting you in UTC±0000.
Inspired by gitdate.
