// 线程安全的时间解析工具
String formatter = "HH:mm:ss dd.MM.yyyy";
String text = "19:30:55 03.05.2015";
Date data = Dates.parse(text, formatter);
// Sun May 03 19:30:55 CST 2015
// 格式化日期
Dates.format(new Date(), formatter)
// 11:00:40 03.04.2020
// 其他用法
Console.info("今天开始时间: %s", Dates.getStartOfDate(new Date()));
Console.info("今天结束时间: %s", Dates.getEndOfDate(new Date()));
Console.info("100天前的时间: %s", Dates.getDate(new Date(), ChronoUnit.DAYS, -100));
Console.info("时间戳: %s", Dates.getTimestamp());
Date oldDate = Dates.parse("19:30:55 03.05.2015", formatter);
Duration duration = Dates.getDuration(new Date(), oldDate);
Console.info("相差天数: %d", duration.toDays());
