Sparkdo.Crontab

Sparkdo.Crontab 是 .NET 10 的 AOT 友好 Cron 表达式解析与 occurrence 计算库。它提供规则的解析、验证、Next、Previous 和 Between，但不执行后台任务或维护调度状态。

dotnet add package Sparkdo.Crontab

using Sparkdo.Crontab;

var cron = Cron.Parse("*/15 * * * *");
var next = cron.Next(new DateTimeOffset(2026, 1, 1, 0, 7, 0, TimeSpan.Zero));

默认格式为“分 时 日 月 周”；可通过 CronFormat.Seconds、Years 或 SecondsAndYears 使用秒和年份字段。字段支持通配符、列表、范围、步长、月份/星期英文名称，以及 L、LW、W、#、nL、R。

var workdayMorning = Cron.Parse("0 9 ? * MON-FRI");
var lastWeekday = Cron.Parse("0 0 LW * *");
var secondMonday = Cron.Parse("0 9 * * MON#2");

日与星期字段使用 AND 关系，星期 0 和 7 都表示周日。Next、Previous 和 Between 默认排除边界；通过 CronOptions.Boundary 可包含起点、终点或两端。

默认按 DateTimeOffset.Offset 计算固定 offset。需要本地时间或 DST 策略时，显式传入 TimeZoneInfo：

var timeZone = TimeZoneInfo.FindSystemTimeZoneById("Asia/Shanghai");
var options = CronOptions.InTimeZone(timeZone);
var next = Cron.DailyAt(9).Next(DateTimeOffset.UtcNow, options);

CronOptions 可控制 DST 无效时间的跳过或前移，以及歧义时间的较早、较晚或双 occurrence 策略。外部输入使用 Cron.TryParse 或 Cron.IsValid 验证；Cron.Parse 的失败会抛出包含表达式、字段、位置和原因的 CronParseException。

完整语法、时间语义、预设与验证命令见仓库 src/crontab/README.md。
