特定时间的今天日期的Kotlin ->时间戳

import java.time.LocalDateTime
import java.time.ZoneId
import java.time.format.DateTimeFormatter

fun main() {
    // 获取今天的日期
    val today = LocalDateTime.now()
    
    // 格式化日期
    val formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")
    val formattedDate = today.format(formatter)
    println("Formatted Date: $formattedDate")
    
    // 转换为时间戳
    val timestamp = today.atZone(ZoneId.systemDefault()).toInstant().toEpochMilli()
    println("Timestamp: $timestamp")
}

val timestamp = today.atZone(ZoneId.of("UTC")).toInstant().toEpochMilli()
