| Name| Description
| xref:BloombergLP/bdlt/IntervalConversionUtil/convertToDatetimeInterval.adoc[`convertToDatetimeInterval`] 
| Return as a `bdlt::DatetimeInterval` the (approximate) value of the specified `interval` truncated toward zero, to microsecond resolution. The behavior is undefined unless the value of `interval`, expressed with nanosecond precision, is within the range of time intervals supported by a `DatetimeInterval` ‐‐ i.e., `DT_MIN * 10ˆ6 <= TI_NSECS <= DT_MAX * 10ˆ6`, where `TI_NSECS` is the total number of nanoseconds in `interval`, `DT_MIN` is the lowest (negative) value expressible by `DatetimeInterval`, and `DT_MAX` is the highest (positive) value expressible by `DatetimeInterval`. Note that, while `bsls::TimeInterval` has nanosecond resolution, `bdlt::DatetimeInterval` has only microsecond resolution.
