+# Make sure that the RECENT_DATE value doesn't get too far behind what the current date is.
+# RECENT_DATE must not be older that 2 years from the build time, or else test_recent_date
+# (from test/test_connection.py) would fail. However, it shouldn't be to close to the build time either,
+# since a user's system time could be set to a little in the past from what build time is (because of timezones,
+# corner cases, etc). As stated in the comment in src/urllib3/connection.py:
+#   When updating RECENT_DATE, move it to within two years of the current date,
+#   and not less than 6 months ago.
+#   Example: if Today is 2018-01-01, then RECENT_DATE should be any date on or
+#   after 2016-01-01 (today - 2 years) AND before 2017-07-01 (today - 6 months)
+# There is also a test_ssl_wrong_system_time test (from test/with_dummyserver/test_https.py) that tests if
+# user's system time isn't set as too far in the past, because it could lead to SSL verification errors.
+# That is why we need RECENT_DATE to be set at most 2 years ago (or else test_ssl_wrong_system_time would
+# result in false positive), but before at least 6 month ago (so this test could tolerate user's system time being
+# set to some time in the past, but not to far away from the present).
