您需要更改区域设置:
# backup original locale
bkp <- Sys.getlocale('LC_TIME')
# change locale
Sys.setlocale('LC_TIME','C')
retest = c("May 31 2014 07:31:46", "May 31 2014 07:32:24", "May 31 2014 07:32:24",
"May 31 2014 07:32:26", "May 31 2014 07:32:33", "May 31 2014 07:32:38",
"May 31 2014 07:32:44", "May 31 2014 07:32:49", "May 31 2014 07:32:52",
"May 31 2014 07:32:53")
a <- strptime(retest, format="%B %d %Y %H:%M:%S")
# restore original locale (if you want...)
Sys.setlocale('LC_TIME',bkp)
