Argument values should be either a number of days (positive to look forward, or negative to look backward), a ~ts~ struct, or a string parseable by ~parse-time-string~ which may omit the time value.
*Selectors:*
*Predicates:*
+ ~ts~ :: Return non-nil if current entry has a timestamp in given period. If no arguments are specified, return non-nil if entry has any timestamp.
+ ~ts-active~ :: Like ~ts~, but only matches active timestamps.
+ ~ts-a~ :: Like ~ts~, but only matches active timestamps.
+ ~ts-inactive~ :: Like ~ts~, but only matches inactive timestamps.
+ ~ts-i~ :: Like ~ts~, but only matches inactive timestamps.
The following selectors, in addition to the keyword arguments, can also take a single argument, a number, which looks backward or forward a number of days. The number can be negative to invert the direction.

*Backward-looking:*
+ ~clocked~ :: Return non-nil if current entry was clocked in given period. If no arguments are specified, return non-nil if entry was clocked at any time. Note: Clock entries are expected to be clocked out. Currently clocked entries (i.e. with unclosed timestamp ranges) are ignored.
