NOTES

The minimum value for the POSIX time format of 315532800 (that is
1980-01-01) was chosen to avoid confusion with ISO dates in the
YYYYMMDD format.

Because named dates are defined with time 0:00:00, using them as
range end excludes the respective day. E.g. using 'today' as upper
range

$ timew sum 2d before today

will not show any intervals of the current day. Use either 'now' or
'tomorrow' in this case:

$ timew sum 2d before now
$ timew sum 2d before tomorrow
