SYNOPSIS

DESCRIPTION

       Timewarrior supports the following datetime formats based on ISO-8601. If times are
       followed by a 'Z', they are assumed to be in UTC, otherwise local time (TZ) is assumed.

           <extended-date> [T <extended-time>]   Extended date, optional extended time
           <date> [T <time>]                     Date, optional time

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
