Hi, Last year, I extended ZTimestamp with a default nanosecond precision (it previously had whole second precision). This makes it a more complete replacement for DateAndTime.
https://github.com/svenvc/ztimestamp https://github.com/svenvc/ztimestamp/commit/de6c5a670ed0c6cb18894b4917383dd9d1dbe503 The goals of ZTimestamp are to be simpler and more efficient (both faster and more compact). A ZTimestamp instance occupies half the space of a DateAndTime instance, its two slots being SmallIntegers. Back in the 32-bit days, the seconds since midnight field was too small for nanoseconds. Now, 64-bit is the default and there is enough room and no speed penalty for working with nanoseconds since midnight. In casual use, you won't see much of a difference, apart from the added detail: ZTimestamp now. "2022-01-27T09:21:20.528695Z" There are ways to convert to the older precision: ZTimestamp now truncated. ZTimestamp now rounded. ZTimestamp nowTruncated. Obviously, other methods and classes now support this added precision (like ZTimestampFormat). If you load or depend on tag/release v25 you get the latest version before this major change. If you encounter any problems please let me know. Sven
