在我电脑上是这样的
<br />
> Sys.time()<br />
[1] "2013-01-24 02:53:06 GMT"<br />
警告信息：<br />
1: In as.POSIXlt.POSIXct(x, tz) : unable to identify current timezone '':<br />
please set environment variable 'TZ'<br />
2: In as.POSIXlt.POSIXct(x, tz) : unknown timezone 'localtime'<br />
</p>
系统信息为：
<br />
sionInfo()<br />

请问如何让Sys.time()获取正确的当前时间
