-The \-c and \-\-condition is a flexible way to filter and get only interesting results. It supports conditions on numerical values, dates, and strings. Dates are given in YYYY\-MM\-DD or YYYY\-MM\-DD HH:MM format.
+The \-c and \-\-condition is a flexible way to filter and get only interesting results. It supports conditions on numerical values, dates, durations and strings. Dates are given in YYYY\-MM\-DD or YYYY\-MM\-DD HH:MM format. Durations look like XhYmZs where X, Y and Z are integers. Any of them may be omitted. For instance, YmZs, XhZs or Ym are accepted.
 The syntax of one expression is "\\fBfield operator value\\fR". The field to test is always the left member of the expression.
 .LP
 The field is a member of the objects returned by the command. For example, a bank account has "balance", "coming" or "label" fields.
