我有以下已知的十六进制值和日期对：
4e754e473248 -> 23:56:23 16/02/2017
4e764e473248 -> 23:57:23 16/02/2017
4e784e473248 -> 23:59:23 16/02/2017
304162483248 -> 00:10:37 17/02/2017
304262483248 -> 00:11:37 17/02/2017
30456f483248 -> 00:14:50 17/02/2017
我无法弄清楚如何从一个转换为另一个。有没有人认识到这种十六进制编码格式？
通过收集数百对，我来到了下面的映射。映射适用于小时，分钟，秒。他们也持有一天，一个月和一年，虽然我无法长时间测试月份和年份。请注意，由于某种原因，序列中的某些数字会被跳过。
第一列是解码值，其他列是不同基数的编码值。

您的表格可以概括为
'0' through '9' (hex 30 through 39) = 0 through 9
'A' through 'Z' (hex 41 through 5A) = 10 through 35
'a' through 'z' (hex 61 through 7A) = 36 through 61
