format_iso8601

<code>format_iso8601()</code> takes a character matrix of date/time components and
converts each component to ISO8601 format. In practice this entails
converting years to a four digit number, and month, day, hours, minutes and
seconds to two-digit numbers. Not available (<code>NA</code>) components are converted
to <code>"-"</code>.

internal

An Electronic Data Capture system (EDC) and Data Standard agnostic
solution that enables the pharmaceutical programming community to develop
Clinical Data Interchange Standards Consortium (CDISC)
Study Data Tabulation Model (SDTM) datasets in R. The reusable algorithms
concept in 'sdtm.oak' provides a framework for modular programming and can
potentially automate the conversion of raw clinical data to SDTM through
standardized SDTM specifications. SDTM is one of the required standards for data
submission to the Food and Drug Administration (FDA) in the United States and
Pharmaceuticals and Medical Devices Agency (PMDA) in Japan. SDTM standards
are implemented following the SDTM Implementation Guide as defined by
CDISC <https://www.cdisc.org/standards/foundational/sdtmig>.

format_iso8601 function

<dl><dt>m</dt>
<dd>A character matrix of date/time components. It must have six
named columns: <code>year</code>, <code>mon</code>, <code>mday</code>, <code>hour</code>, <code>min</code> and <code>sec</code>.</dd>
<dt>.cutoff_2000</dt>
<dd>An integer value. Two-digit years smaller or equal to
<code>.cutoff_2000</code> are parsed as though starting with <code>20</code>, otherwise parsed as
though starting with <code>19</code>.</dd></dl>
