NAME

       ods-timing - OpenDNSSEC timing specification

SYNOPSIS

       /etc/opendnssec/conf.xml
       /etc/opendnssec/kasp.xml
       /etc/opendnssec/zonelist.xml

DESCRIPTION

       The  configuration  files  of  OpenDNSSEC  need  to  have timing descriptions, notably for
       periods.  These descriptions follow ISO 8601 with exceptions for the duration of  a  month
       and  a  year,  as these periods would be allowed to vary if ISO 8601 were strictly adhered
       to.

       Durations  are  represented  by   the   format   P[n]Y[n]M[n]DT[n]H[n]M[n]S.    In   these
       representations,  the  [n] is replaced by the value for each of the date and time elements
       that follow the [n]. Leading zeros are not required. The capital letters P, Y, M, W, D, T,
       H, M and S are designators for each of the date and time elements and are not replaced

       P      is  the  duration  designator (historically called "period") placed at the start of
              the duration representation.

       Y      is the year designator that follows the value for the number of years.

       M      is the month designator that follows the value for the number of months.

       W      is the week designator that follows the value for the number of weeks.

       D      is the day designator that follows the value for the number of days.

       T      is the time designator that precedes the time components of the representation.

       H      is the hour designator that follows the value for the number of hours.

       M      is the minute designator that follows the value for the number of minutes.

       S      is the second designator that follows the value for the number of seconds.

       For example, P3Y6M4DT12H30M5S represents a duration of  "three  years,  six  months,  four
       days,  twelve  hours,  thirty minutes, and five seconds". Date and time elements including
       their designator may be omitted if their value is zero, and lower order elements may  also
       be  omitted  for  reduced  precision.  For  example,  P23DT23H and P4Y are both acceptable
       duration representations.

EXCEPTION

       A year or month vary in duration depending on the current date. For OpenDNSSEC, we  assume
       fixed values

       One month
              is assumed to be 31 days.

       One year
              is assumed to be 365 days.

       This  exception  may  or  may not change in future releases of OpenDNSSEC.  The reason for
       making this exception is to avoid complicating this software in a way that  may  not  meet
       any practical need.
