我有一个时刻字符串如下：
String build_time=2017-11-20T21:27:03Z
我想将其转换成信号出现时间以毫秒为单位按照PST时区，使得我的结果是：
long build_time_ms=1511299623000
我怎样才能做到这一点？
Answer 1:
你可以做到这一点使用Java的java.time.*包。 下面是从运行通过码头工人常规工作的脚本和输出。 我还没有内詹金斯想这虽然和脚本可能需要添加适当def语句来避免管道序列化问题
脚本
import java.time.*
// build time as string
build_time='2017-11-20T21:27:03Z'
// parse and get epoch
time=Date.parse("yyyy-MM-dd'T'HH:mm:ss'Z'", build_time)
// get epoch milis
epoch_milis = time.getTime()
// create UTC local time
local_dt = LocalDateTime.ofInstant(Instant.ofEpochMilli(epoch_milis), ZoneId.of('UTC'));
// created zoned time out of UTC time
zoned_dt = local_dt.atZone(ZoneId.of('America/Los_Angeles'))
// get offset in milis
offset_ms = zoned_dt.getOffset().getTotalSeconds() * 1000
// add to UTC epoc
local_timestamp = epoch_milis + offset_ms
println "Time is ${local_timestamp}"
脚本输出，在常规运行REPL
$ docker run --rm -it groovy

此外，在你的榜样，你给的1511299623000毫秒，这似乎是提前时间戳24小时的结果，观察JavaScript控制台，从您的示例输入
new Date('2017-11-20T21:27:03Z')
>> Tue Nov 21 2017 08:27:03 GMT+1100 (AEDT)
new Date(1511299623000)
>> Wed Nov 22 2017 08:27:03 GMT+1100 (AEDT)
