Issue:
Warn when since/until options are used with relative time
We should clearly warn when user (e.g. by a copy & paste accident)
specifies `--since` or `--until` options together with relative
time specification such as `last week` as it's not clear what the
desired result should be. Refusing to guess and suggesting to the
user to choose seems to be the most straightforward solution.
