The API now supports a POST route for adding records. Therefore
checking for already existing records and including them in a PATCH
request is no longer necessary.
Adding this to at least partially prevent the virtually nonexistent possibility of timestamp and _utc_date() mismatch. If the normal date -u -d does not get converted (looking at you Solaris!), the poor man's method with manipulating the _utc_date() string output kicks in.
