get-date:
# We use the date to label caches. A cache is a a "hit" if the date is the
# request binary and date are the same as what is stored in the cache.
# This essentially means the first job to run on a given day for a given
# binary will always be a "miss" and will have to build the binary then
# upload it as that day's binary to upload. While this isn't the most
# efficient way to do this, the alternative was to run take a hash of the
# `src` directory contents and use it as a hash. We found there to be bugs
# with the hash function where this task would timeout. This approach is
# simple, works, and still provides some level of caching.
