:relfileprefix: ../../../
:mrdocs:

Load into the specified `result` the relative time computed as the difference between the specified absolute `datetime` and the epoch. Return 0 on success, and a non‐zero value (with no effect on `result`) if `datetime ‐ epoch() < DatetimeInterval()` or `datetime` cannot be represented in the destination format on all supported platforms (i.e., the computed `*result` is not representable as a 32‐bit `int`). Note that `datetime` is assumed to use Coordinated Universal Time (UTC) as a reference.
