The idea was good, but it applied the second-precise date format everywhere.
This broke dates on apps and apks, which have the format yyyy-MM-dd on the
index.
Fix this by having two sets of funcs in Utils, one for dates (precise to a
day) and one for times (precise to a second). We should use the latter for
dates we ourselves measure, like the last repo update time.
