This completes the exhaustive refactoring of foundational temporal types from Joda-Time to the native java.time API across the entire codebase.
- Replaced org.joda.time.DateTime, Instant, LocalDate, and Duration with java.time equivalents.
- Audited and updated Clock implementations (FakeClock, SystemClock). Added nowMillis(), nowDate(), and nowDateTime() to eliminate repetitive conversions and maintain parallel naming.
- Replaced ZonedDateTime with OffsetDateTime globally per go/avoid-zdt. OffsetDateTime is a better fit as we use a hardcoded ZoneOffset.UTC throughout the system, making geographical time zone rules (like daylight saving time) irrelevant and preventing serialization ambiguities. Added a presubmit check.
- Completely removed all transitional bridge methods from DateTimeUtils and deleted obsolete converters (e.g., DateTimeConverter).
- Updated testing infrastructure, Apache Beam pipelines, custom JCommander parameters, and networking modules to solely rely on java.time primitives.
- Retained the lone necessary org.joda.time.Instant usage in SafeBrowsingTransforms required by the Apache Beam API.
- Cleared Gradle lockfiles and removed the joda-time dependency entirely from the build configuration.
* Migrates core classes (Clock, Sleeper, TransactionManager) and extensive domain models from Joda-Time to java.time.
* Restores original public API method names while substituting parameters/return values with `java.time.Instant`.
* Updates JAXB XJC `bindings.xjb` to natively generate `java.time.Instant` and `java.time.LocalDate`, eliminating `toDateTime` wrapper methods.
* Fixes XML serializers (`DateAdapter`) to robustly convert OffsetDateTime timezone strings to UTC.
* Cleans up redundant imports and Checkstyle failures across the codebase.
Remaining Joda-Time surface area to migrate in future tasks:
* Command-line parameters (e.g. `DateTimeParameter`, `DateParameter`, `IntervalParameter`) in `google.registry.tools.params`.
* EPP/RDAP flow testing infrastructure (`EppTestCase`, `RdapActionBaseTestCase`, `FlowTestCase`).
* Beam pipelines and Load Testing modules (`Spec11PipelineTest`, `RdePipelineTest`, `RegistryJpaReadTest`, `EppClient`).
* Utility bridges and converters (`DateTimeUtils.toDateTime/toInstant`, `DateTimeConverter`, `UtcDateTimeAdapter`).
* Remaining UI Console tests and Actions.
This commit migrates the BSA, DNS, batch, and reporting packages from Joda-Time
to java.time. Key changes include:
- Updated Sleeper, Clock, and BigqueryUtils to use java.time types natively.
- Refactored models like RdeRevision and Tld to eliminate redundant Joda
conversions, utilizing new DateTimeUtils static utilities for LocalDate.
- Improved test safety by replacing dynamic Instant.now() calls with static
parsed constants.
- Migrated temporal arithmetic in test suites to use DateTimeUtils convenience
methods (plusDays, minusDays).
- Updated BigqueryUtils serialization to preserve millisecond precision and
formatting for large years, ensuring consistency with previous Joda behavior.
- Enhanced code readability by converting long concatenated strings to Java
text blocks in LordnLogTest.
- Resolved environmental test failures in SyncRegistrarsSheetTest by
synchronizing the FakeClock with the JPA extension.
- Updated project engineering standards (GEMINI.md) to prefer Truth's
.hasValue() for Optional assertions.
Verified with a clean full build and all relevant test suites passing.
This comprehensive refactor continues the migration from Joda-Time to java.time (Instant), focusing on core timestamp models, transition properties, and their integration across the codebase.
Key changes:
- Migrated CreateAutoTimestamp and UpdateAutoTimestamp to use Instant internally, providing Joda-Time bridge methods for backward compatibility.
- Updated TimedTransitionProperty to handle Instant-based transition maps and updated corresponding Hibernate UserTypes (TimedTransitionBaseUserType).
- Migrated GracePeriod, BillingBase, BillingEvent, PollMessage, and PendingActionNotificationResponse fields (e.g., expirationTime, eventTime) to Instant.
- Migrated additional core entities (DomainBase, Registrar, HostBase, LaunchNotice, BsaLabel, DomainTransactionRecord) to use Instant for registrationExpirationTime, lastTransferTime, creationTime, etc.
- Updated Tld and FeatureFlag models to use Instant for claimsPeriodEnd, bsaEnrollStartTime, and status transitions.
- Enhanced CLI tools and parameters (TransitionListParameter, InstantParameter, RequestParameters) to support Instant-based input and output.
- Updated EntityYamlUtils with custom Instant serializers/deserializers to maintain format consistency (e.g., .SSSZ precision) required for YAML-based tests.
- Implemented UtcInstantAdapter to ensure JAXB XML serialization maintains millisecond accuracy, matching legacy Joda-Time behavior.
- Resolved Hibernate 6 type mismatches in JPQL and Native queries by ensuring consistent use of Instant for comparisons.
- Updated GEMINI.md with project-specific engineering standards, including the 'one commit per PR' mandate, full-build validation requirement, and commit message style rules.
- Cleaned up unnecessary @JsonIgnore and @JsonProperty annotations that were previously added to methods with parameters or redundant fields.
- Refactored DateTimeUtils to use strongly-typed overloads and standardized naming (earliestOf, latestOf) while avoiding type erasure clashes.
- Cleaned up fully qualified calls to toDateTime and toInstant by adding static imports across core model and flow files.
- Refactored test suites to use clock.now() (Instant) instead of nowUtc() (DateTime) and removed custom Truth subjects in favor of standard assertions.
Our existing precision is milliseconds so we want to stick with that for
Instants. If we want to increase the precision globally after that we can do so
all in one go post-migration, but for now, it would be a bad thing to have mixed
precision going on just depending on whether a class happens to be migrated yet
or not.
This PR also migrates all existing DateTime.nowUtc() calls to use the Clock
interface, so that when they are migrated they will get the benefit of this
precision-setting as well.
BUG= http://b/496985355
java.time has been around since Java 8 and was based on joda DateTime, so this
is an overdue migration. We're migrating specifically to Instant in most places
rather than ZonedDateTime because we were always using DateTimes in UTC to
reference a specific instant, which is exactly what Instants are
for. ZonedDateTime set to UTC may still be useful in some places that are heavy
on date math (especially in tests).
There is a lot more work to be done after this, but I wanted to put together a
manual PR showing my overall approach for how to do the migration that I can
then hopefully follow along with AI to continue making these changes throughout
the codebase. The basic approach is to migrate a small number of methods at a
time, marking the old methods as @Deprecated when possible (not always possible
because of @InlineMe restrictions). This PR doesn't yet migrate any DateTime
fields in the model classes, so that's the one remaining type of refactor to
figure out after this. We won't be changing how any of the data is actually
stored in the database.

* Break circular dependency between core and util
Created a new :common project and moved a minimum
number of classes to break the circular dependency
between the two projects. This gets rid of the
gradle lint dependency warnings.
Also separated api classes and testing helpers into
separate source sets in :common so that testing
classes may be restricted to test configurations.
