ods-timing - OpenDNSSEC timing specification
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
M is the month designator that follows the value for the number of
W is the week designator that follows the value for the number of
D is the day designator that follows the value for the number of
T is the time designator that precedes the time components of the
H is the hour designator that follows the value for the number of
M is the minute designator that follows the value for the number
S is the second designator that follows the value for the number
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
A year or month vary in duration depending on the current date. For
OpenDNSSEC, we assume fixed values

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.
