Use 'hg ci -d "1000000 0"' in tests to circumvent problem with leading zero.
Some systems show "Thu Jan 01" instead of "Thu Jan 1", which breaks tests.
Using "1000000" yields "Mon Jan 12 13:46:40 1970", which looks the same on
all systems.

# in theory, we shouldn't need the "yes k" below, but it prevents
# this test from hanging when "hg update" erroneously prompts the
# user for "keep or delete"
yes k | hg update 1
# we exit with 0 to avoid the unavoidable SIGPIPE from above causing
# us to fail this test
exit 0
