precision

calculate

• truncateNanoseconds: Truncate nanoseconds since the Unix epoch to the precision a store can actually hold.

convert

• fromDotNetTicks: Convert .NET DateTime.Ticks back to an ISO 8601 instant string.
• fromExcelSerial: Convert an Excel day serial back to an ISO 8601 instant string.
• fromFileTime: Convert a Windows FILETIME back to an ISO 8601 instant string.
• fromNanoseconds: Convert nanoseconds since the Unix epoch back to an ISO 8601 string.
• fromNtpTimestamp: Convert a 64-bit NTP timestamp (RFC 5905) back to an ISO 8601 instant string.
• fromPgMicroseconds: Convert PostgreSQL’s internal timestamptz value back to an ISO 8601 instant string.
• toDotNetTicks: Convert an ISO 8601 instant string to .NET DateTime.Ticks.
• toExcelSerial: Convert an ISO 8601 instant string to an Excel day serial.
• toFileTime: Convert an ISO 8601 instant string to a Windows FILETIME.
• toNanoseconds: Convert an ISO 8601 instant string to nanoseconds since the Unix epoch.
• toNtpTimestamp: Convert an ISO 8601 instant string to a 64-bit NTP timestamp (RFC 5905).
• toPgMicroseconds: Convert an ISO 8601 instant string to PostgreSQL’s internal timestamptz value.

format

• formatNanoseconds: Format nanoseconds since the Unix epoch as a decimal string, for JSON and other text transports.

parse

• parseNanoseconds: Parse a decimal string produced by formatNanoseconds — typically one field of a JSON payload — back to nanoseconds since the Unix epoch.

validate

• isValidInstant: Validate whether a string is an ISO 8601 instant string the precision/ namespace accepts.
• isValidNanoPattern: Validate whether a string is a nanosecond timestamp parseNanoseconds will parse.
• isValidNanoseconds: Validate whether a value is an epoch-nanosecond bigint the precision/ namespace accepts.
