cloud.opencode.base.date.OpenDate

public final class OpenDate extends Object

Core Date Utility Class - Main Entry Point for OpenCode Date Module 核心日期工具类 - OpenCode日期模块的主入口

This class provides comprehensive date/time operations as the main facade for the date module. It is designed to be the one-stop solution for most date/time needs, comparable to Commons DateUtils + Hutool DateUtil.

此类提供全面的日期时间操作，作为日期模块的主要门面。设计为满足大多数日期时间需求的一站式解决方案，可与Commons DateUtils + Hutool DateUtil相媲美。

Features | 主要功能:

Current time access - 当前时间访问
Date/time creation - 日期时间创建
Smart parsing - 智能解析
Formatting - 格式化
Truncation and rounding - 截断和取整
Add/subtract operations - 加减操作
Range and comparison - 范围和比较
Boundary calculations - 边界计算

Usage Examples | 使用示例:

// Current time
LocalDate today = OpenDate.today();
LocalDateTime now = OpenDate.now();
long millis = OpenDate.currentTimeMillis();

// Create dates
LocalDate date = OpenDate.of(2024, 1, 15);
LocalDateTime dateTime = OpenDate.of(2024, 1, 15, 14, 30, 0);

// Smart parsing
LocalDateTime dt1 = OpenDate.parse("2024-01-15 14:30:45");
LocalDateTime dt2 = OpenDate.parse("20240115143045");

// Formatting
String formatted = OpenDate.format(now);
String chinese = OpenDate.formatChinese(now);

// Truncation
LocalDateTime truncated = OpenDate.truncateToDay(now);

// Add/subtract
LocalDateTime future = OpenDate.plusDays(now, 7);

// Boundaries
LocalDate monthStart = OpenDate.startOfMonth(today);
LocalDate monthEnd = OpenDate.endOfMonth(today);

Performance | 性能特性:

All methods are static and stateless - 所有方法都是静态和无状态的
Cached formatters for performance - 缓存格式化器以提高性能

Security | 安全性:

Thread-safe: Yes - 线程安全: 是
Null-safe: Yes (with explicit null checks) - 空值安全: 是（有明确的空值检查）

Since:

JDK 25, opencode-base-date V1.0.0
