origin_to_squids

datetime_to_squids

POSIXt_to_squids

For convenience, <code>origin_to_squids()</code>, <code>datetime_to_squids()</code>, and
<code>POSIXt_to_squids()</code> can all be used (i.e. they're aliases for the same
function). For more information, see <code>squids()</code>. For conversion
the other way around, see <code>squids_to_origin()</code>.

It is often useful to produce short, quasi-unique
identifiers (SQUIDs) without the benefit of a central authority to
prevent duplication. Although Universally Unique Identifiers (UUIDs)
provide for this, these are also unwieldy; for example, the most used UUID,
version 4, is 36 characters long. SQUIDs are short (8 characters) at the
expense of having more collisions, which can be mitigated by combining them
with human-produced suffixes, yielding relatively brief, half
human-readable, almost-unique identifiers (see for example the identifiers
used for Decentralized Construct Taxonomies; Peters & Crutzen,
2024 <doi:10.15626/MP.2022.3638>). SQUIDs are the number of
centiseconds elapsed since the beginning of 1970 converted to a base 30
system. This package contains functions to produce SQUIDs as well as
convert them back into dates and times.
