转载自:LocalDateTime To Timestamp Epoch Seconds And Milliseconds
Convert LocalDateTime to seconds since January 1, 1970, 00:00:00 GMT
val now = LocalDateTime.now(ZoneOffset.UTC) // LocalDateTime to epoch seconds val seconds = now.atZone(ZoneOffset.UTC).toEpochSecond()) // Epoch seconds to LocalDateTime val newNow = LocalDateTime.ofInstant(Instant.ofEpochSecond(seconds), ZoneOffset.UTC)
Convert LocalDateTime to milliseconds since January 1, 1970, 00:00:00 GMT
// LocalDateTime to epoch milliseconds val milliseconds = now.atZone(ZoneOffset.UTC)?.toInstant()?.toEpochMilli() // epoch milliseconds to LocalDateTime val newNow = LocalDateTime.ofInstant(Instant.ofEpochMilli(milliseconds), ZoneOffset.UTC)
