在Common Lisp中格式化包括GMT偏移量的时间戳？-解网

问：

使用带有“本地时间”包的 common lisp，我正在尝试格式化包含 GMT 偏移量的时间戳。该文档包含一个“：gmt-offset”格式参数，但使用它会生成错误。我查看了 github 上的源代码，case 语句似乎包括：gmt-offset。我做错了什么吗？我是否获得了没有 gmt-offset 的旧版本的本地时间？

(ql:quickload "local-time")
(local-time:format-timestring nil (local-time:now) :format
    '((:year 4)  #\.
      (:month 2) #\.
      (:day 2)   #\.
      (:hour 2)  #\.
      (:min 2)   #\.
      (:sec 2)   #\.
      (:msec 3)  #\-
      (:gmt-offset)))

在 SBCL 2.3.4 中加载它给了我：

debugger invoked on a SB-KERNEL:CASE-FAILURE @225F39AB in thread #<THREAD "main thread" RUNNING {10044C00A3}>: :GMT-OFFSET fell through ECASE expression. Wanted one of (:NSEC :USEC :MSEC :SEC :MIN :HOUR :HOUR12 :DAY :WEEKDAY :MONTH :YEAR :ISO-WEEK-YEAR ...).

Type HELP for debugger help, or (SB-EXT:EXIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
  0: [ABORT] Exit debugger, returning to top level.

(LOCAL-TIME::%CONSTRUCT-TIMESTRING #<unavailable argument> #<unavailable argument> #<unavailable argument>)
   source: (ECASE (IF (CONSP FMT) (CAR FMT) FMT) (:NSEC NSEC) (:USEC (FLOOR NSEC 1000)) (:MSEC (FLOOR NSEC 1000000)) (:SEC SEC) (:MIN MINUTE) (:HOUR HOUR) (:HOUR12 (1+ (MOD (1- HOUR) 12))) (:DAY DAY) (:WEEKDAY WEEKDAY) (:MONTH MONTH) ...)

时间戳 lisp common-lisp gmt

(ql:quickload "local-time")
(local-time:format-timestring nil (local-time:now) :format
                  '((:year 4) #\.
                (:month 2) #\.
                (:day 2) #\.
                (:hour 2) #\.
                (:min 2) #\.
                (:sec 2) #\.
                (:msec 3) #\-
                :gmt-offset
                ))
