CFtime-class

CF Metadata Conventions time representation

Support for all calendars as specified in the Climate and Forecast
(CF) Metadata Conventions for climate and forecasting data. The CF Metadata
Conventions is widely used for distributing files with climate observations
or projections, including the Coupled Model Intercomparison Project (CMIP)
data used by climate change scientists and the Intergovernmental Panel on
Climate Change (IPCC). This package specifically allows the user to work
with any of the CF-compliant calendars (many of which are not compliant with
POSIXt). The CF time coordinate is formally defined in the CF Metadata
Conventions document available at <https://cfconventions.org/Data/cf-conventions/cf-conventions-1.11/cf-conventions.html#time-coordinate>.

CFtime-class function

<dl>
<dt><code>datum</code></dt>
<dd>CFdatum. The origin upon which the <code>offsets</code> are based.</dd></dl>
<dt><code>resolution</code></dt>
<dd>numeric. The average number of time units between offsets.</dd>
<dt><code>offsets</code></dt>
<dd>numeric. A vector of offsets from the datum.</dd>
<dt><code>bounds</code></dt>
<dd>Optional, the bounds for the offsets. If not set, it is the
logical value <code>FALSE</code>. If set, it is the logical value <code>TRUE</code> if the bounds
are regular with respect to the regularly spaced offsets (e.g. successive
bounds are contiguous and at mid-points between the offsets); otherwise a
<code>matrix</code> with columns for <code>offsets</code> and low values in the first row, high
values in the second row.</dd>
