sync_datetime 0.1.6

Dart & Flutter DateTime utilities for UTC timezone conversion, ISO 8601 parsing, client-server synchronization, REST API timestamps, date calculations, and calendar math.

0.1.6

• Improve fromServer parser timezone handling logic by updating the timezone regex matching pattern.
• Support all valid ISO 8601 offset strings including basic formats without colons (e.g. +0000) and lowercase timezone indicators.
• Expand test coverage validating various offset string patterns.

0.1.5

• Add Core Utilities: today(), todayUtc(), nowUtc(), startOfDay(), endOfDay(), stripDate(), stripTime(), and copyWith().
• Add Comparison Utilities: isSameDay(), isSameMonth(), isSameYear(), daysBetween(), and daysInMonth(), isLeapYear().
• Add Difference Helpers: differenceInYears(), differenceInDays(), differenceInHours(), differenceInMinutes(), differenceInSeconds(), and differenceInMilliseconds().
• Add Server Synchronization Helper: normalizeServerTimestamp().
• Enforce strict timezone matching across all comparison and difference APIs, throwing ArgumentError on mismatches.
• Expand test coverage and update package examples.

0.1.4

• Add toServerParts static helper method to serialize a DateTime into a ServerDateTimeParts object (containing separate UTC date and time strings).
• Export ServerDateTimeParts from the main library entry point.
• Update documentation and example script to showcase toServerParts.

0.1.3

• Add fromServerParts static helper method to parse separate date and time strings.
• Update documentation and example script to showcase fromServerParts.

0.1.2

• Update README version references and documentation.

0.1.1

• Add repository metadata to pubspec.yaml.
• Fix potential 1-hour parsing offset bug under Daylight Saving Time (DST) transitions in fromServer.
• Improve parameter naming on toUtc and toServer for clarity.
• Implement detailed ArgumentError.value debugging information.
• Add additional test coverage for negative timezone offset parsing.

0.1.0

• Initial version.
• Implement reliable, predictable DateTime synchronization methods: toUtc, fromUtc, toServer, fromServer, and combine.
• Enforce strict parameter validation and robust parsing of ISO 8601 strings (handling both explicit and implicit UTC formats).
