Relative and absolute formats are parsed by `date -d`. Systemd OnCalendar values are passed through directly.
Note: `date -d` does not technically like the "*in* 5 minutes" syntax. `systab` removes the offending "in".
Note: `date -d` does not technically like "*in* 5 minutes" or "*at*" between day and time. `systab` strips "in" and "at" before passing to `date -d`.
