1. 事情起因:
本人这久在关注一个地方域名( .ren，由于某些因素，此处用 来代表域名)，
因域名已经过期，有打算抢注的意愿，就等域名注册机构删除后我来抢注册了。
( *.ren)
注册日期 2014年10月15日
到期日期 2017年10月30日
到期日期 10月30日
每天的查询记录:
2017.11.08 未删
2017.11.28 未删
2017.11.30 未删
2017.12.01 未删
2017.12.02 未删
2017.12.03 未删
2017.12.04 未删
无耐，()2017-12-05) 今早10点多一看，域名竟然被抢注册了。
2017.12.05 注册了
突然间这种失落啊。。。 关注这么久，竟然失之交臂了。。。
有点欲哭无泪，万念俱灰的感觉

换算成北京时间:

Creation Date:2017-12-05 02:07:44

折腾了下，突然明白了。原来是北京时间5号的凌晨2时左右抢注的啊.
哎，这久花的精力和时间白白浪费和。
期初一直没怎么留意和关注过域名展示的这种时间格式，(我也太孤陋寡闻了) 哎。
究其原因，还没有深刻理解 yyyy-MM-dd’T’HH:mm:ss.SSSZ 这种时间格式中的T和Z所表示的含义。
2. yyyy-MM-dd’T’HH:mm:ss.SSSZ 时间格式
下面来着重认识一下：
Date Time String Format
ECMAScript defines a string interchange format for date-times based upon a simplification of the ISO 8601 Extended Format. The format is as follows: YYYY-MM-DDTHH:mm:ss.sss*Z*
Where the fields are as follows:
YYYY |
is the decimal digits of the year 0000 to 9999 in the Gregorian calendar. |
|---|---|
- |
"-" (hyphen) appears literally twice in the string. |
MM |
is the month of the year from 01 (January) to 12 (December). |
DD |
is the day of the month from 01 to 31. |
T |
"T" appears literally in the string, to indicate the beginning of the time element. |
HH |
is the number of complete hours that have passed since midnight as two decimal digits from 00 to 24. |
: |
":" (colon) appears literally twice in the string. |
mm |
is the number of complete minutes since the start of the hour as two decimal digits from 00 to 59. |
ss |
is the number of complete seconds since the start of the minute as two decimal digits from 00 to 59. |
. |
"." (dot) appears literally in the string. |
sss |
is the number of complete milliseconds since the start of the second as three decimal digits. |
"Z" |
is the time zone offset specified as “Z” (for UTC) or either “+” or “-“ followed by a time expression HH:mm |
上面这个时间格式就是带T和Z这种是ISODATE .
