# have a couple of problems:
# 1) The strings generated by isotime are used in tokens and other public
# APIs that we can't change without a deprecation period. The strings
# generated by isoformat are not the same format, so we can't just
# change to it.
# 2) The strings generated by isoformat do not include the microseconds if
# the value happens to be 0. This will likely show up as random failures
# as parsers may be written to always expect microseconds, and it will
# parse correctly most of the time.
