as.timespan

Datetimes and timestamps are invariably an imprecise notation, with any
partial representation implying some amount of uncertainty. To handle this,
'parttime' provides classes for embedding partial missingness as a central
part of its datetime classes. This central feature allows for more ergonomic
use of datetimes for challenging datetime computation, including
calculations of overlapping date ranges, imputations, and more thoughtful
handling of ambiguity that arises from uncertain time zones. This package was
developed first and foremost with pharmaceutical applications in mind, but
aims to be agnostic to application to accommodate general use cases just as
conveniently.

<dd>an object to cast</dd>
<dt>...</dt>
<dd>Additional arguments passed to <code>format</code> when a function is
provided.</dd>
<dt>format</dt>
<dd>a <code>function</code> or <code>character</code> value. If a
<code>function</code>, it should accept a character vector and return a matrix of
parttime components. If a <code>character</code> it should provide a regular
exprssion which contains capture groups for each of the parttime
components. See parse_to_parttime_matrix's <code>regex</code> parameter
for more details.</dd></dl>
