如何转换ISO时间以显示在Android Studio中发布了几小时的内容？

Question

我正在使用要转换的ISO格式的时间，然后显示该项目是多少小时前获得的。我已经为此编写了代码，但是由于某种原因返回时结果不正确。例如，如果时间是一分钟前，则表示三个小时前！我的问题是格式无法正常工作，但ISO转换有效，但是格式错误！

这是我上课的时间格式：

class ReformatTime {

@SuppressLint("SimpleDateFormat")
fun convertISOTime(time: String): String {
    val inputPattern = "yyyy-MM-dd'T'HH:mm:ss.SSSSSSS'Z'"
    val inputFormat = SimpleDateFormat(inputPattern)
    return getTimeAgo(inputFormat.parse(time).time)
}

companion object {
    private const val SECOND_MILLIS = 1000
    private const val MINUTE_MILLIS = 60 * SECOND_MILLIS
    private const val HOUR_MILLIS = 60 * MINUTE_MILLIS
    private const val DAY_MILLIS = 24 * HOUR_MILLIS
}

private fun getTimeAgo(time: Long): String {
    var time = time

    if (time < 1000000000000L) {
        // if timestamp given in seconds, convert to millis
        time *= 1000
    }

    val now = System.currentTimeMillis()
    if (time > now || time <= 0) return ""

    val diff = now - time
    return when {
        diff < MINUTE_MILLIS -> "just now"
        diff < 2 * MINUTE_MILLIS -> "a minute ago" 
        diff < 50 * MINUTE_MILLIS -> "${diff / MINUTE_MILLIS}  minutes ago"
        diff < 90 * MINUTE_MILLIS -> "an hour ago"
        diff < 24 * HOUR_MILLIS -> "${diff / HOUR_MILLIS} hours ago"
        diff < 48 * HOUR_MILLIS -> "yesterday"
        else -> "${diff / DAY_MILLIS} days ago"
    }
}}
