如何解析带日期的时区

timezone parsing date bash linux

如何让date实用程序解析时区字符串?

$>date -d "2018-02-21T02:22:33.221" "+%Y-%m-%dT%H:%M:%S.%3N %Z"
2018-02-20T14:22:33.221 EST

但是

$>date -d "2018-02-21T02:22:33.221 EST" "+%Y-%m-%dT%H:%M:%S.%3N %Z"
date: invalid date `2018-02-21T02:22:33.221 EST'

这是本地信息:

$>uname -r
2.6.32-696.13.2.el6.x86_64

$>date
Tue Jan 16 09:58:52 EST 2018

$>date --version

ISO8601 允许您替换 T 有空间。只要这样做,您的命令就会正常工作:

# date -d "2018-02-21T02:22:33.221 EST" "+%Y-%m-%dT%H:%M:%S.%3N %Z"
date: invalid date `2018-02-21T02:22:33.221 EST'

但是:

# date -d "2018-02-21 02:22:33.221 EST" "+%Y-%m-%d %H:%M:%S.%3N %Z"
2018-02-21 10:22:33.221 MSK

date -d date +format ,它只能接受来自 man date

  -d, --date=STRING
          display time described by STRING, not `now'
DATE STRING
   The  --date=STRING  is  a  mostly  free  format  human  readable  date string such as "Sun, 29 Feb 2004 16:21:42 -0800" or
   "2004-02-29 16:21:42" or even "next Thursday".  A date string may contain items indicating calendar  date,  time  of  day,
   time  zone,  day  of week, relative time, relative date, and numbers.  An empty string indicates the beginning of the day.
   The date string format is more complex than is easily documented here but is fully described in the info documentation.
