Hi, As suggested by the git book/tutorial I cloned "simplegit-progit" to learn using git. The issue: git log --since=5.years yields 2 commits, while git log --since=6.years yields 3 commits, despite the "Date" in both cases being March 2008. Is it a bug? Using Fedora 20 amd64 with git version 1.8.4.2 Details: //==> FIVE YEARS simplegit-progit$ git log --since=5.years commit ca82a6dff817ec66f44342007202690a93763949 Author: Scott Chacon <schacon@xxxxxxxxx> Date: Mon Mar 17 21:52:11 2008 -0700 changed the verison number commit 085bb3bcb608e1e8451d4b2432f8ecbe6306e7e7 Author: Scott Chacon <schacon@xxxxxxxxx> Date: Sat Mar 15 16:40:33 2008 -0700 removed unnecessary test code //<== FIVE YEARS //==> SIX YEARS simplegit-progit$ git log --since=6.years commit ca82a6dff817ec66f44342007202690a93763949 Author: Scott Chacon <schacon@xxxxxxxxx> Date: Mon Mar 17 21:52:11 2008 -0700 changed the verison number commit 085bb3bcb608e1e8451d4b2432f8ecbe6306e7e7 Author: Scott Chacon <schacon@xxxxxxxxx> Date: Sat Mar 15 16:40:33 2008 -0700 removed unnecessary test code commit a11bef06a3f659402fe7563abf99ad00de2209e6 Author: Scott Chacon <schacon@xxxxxxxxx> Date: Sat Mar 15 10:31:28 2008 -0700 first commit //<== SIX YEARS -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
