add Temporal faker for java.time-based date/time generation

[TheJavaGuy]

Overview

The Temporal faker generates random date/time values using the modern Java 8+ java.time API. It complements the existing DateAndTime provider (which uses legacy java.util.Date/Calendar) without modifying it.

Use Cases

• Testing systems that use java.time types (Instant, LocalDateTime, LocalDate, etc.)
• Generating realistic timestamps for event sourcing and audit logs
• Creating random scheduling data (appointments, bookings, reservations)
• Birthday and age-related test data using LocalDate
• Duration and period generation for SLA/timeout testing
• Timezone-aware test scenarios

Files to create/modify

Component	Path
Java Class	src/main/java/org/thejavaguy/javafaker/Temporal.java
Test Class	src/test/java/org/thejavaguy/javafaker/TemporalTest.java
Registration	src/main/java/org/thejavaguy/javafaker/Faker.java

No YAML file needed — all methods are purely algorithmic.

Methods

• futureInstant(long atMost, ChronoUnit unit) — future Instant
• futureInstant(long atMost, long minimum, ChronoUnit unit) — future Instant with minimum
• futureInstant(long atMost, ChronoUnit unit, Instant referenceInstant) — future Instant relative to reference
• pastInstant(...) — corresponding past variants
• instantBetween(Instant from, Instant to) — random Instant in range
• futureLocalDateTime / pastLocalDateTime / localDateTimeBetween — LocalDateTime variants
• futureLocalDate / pastLocalDate / localDateBetween / birthdayLocalDate — LocalDate variants
• localTime() — random LocalTime
• duration(long maxSeconds) — random Duration
• period(int maxDays) — random Period
• zoneId() — random IANA ZoneId
