英文:
Convert zoned timestamp to com.google.protobuf.Timestamp
问题
在我正在使用Swagger创建的自定义API中，我需要输入一个时间戳。
在我的YAML文件中，我已将输入参数的格式定义为date-time，如Swagger网页上所述日期时间 - 如RFC 3339第5.6节定义的日期时间表示法，例如2017-07-21T17:32:28Z。
我想将生成的带时区的时间戳转换为com.google.protobuf.Timestamp，但我不知道如何操作，需要帮助。我正在使用Kotlin。
到目前为止，我尝试了一些从StackOverflow中提取的Java示例（转换为Kotlin后），例如：
System.out.println(SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXXX")
.format(Date()))
和
val withoutTimezone = zoneDateTime.toLocalDateTime()
val timestamp = Timestamp.valueOf(withoutTimezone)
由于我需要将输入参数格式转换为com.google.protobuf.Timestamp，因此上述示例均不起作用。
有关如何转换时间戳的任何帮助将不胜感激。
英文:
In my custom API that I am creating using Swagger, I need to input a timestamp.
In my YAML file I have defined the format of my input parameter as date-time as mentioned on the Swagger webpage date-time – the date-time notation as defined by RFC 3339, section 5.6, for example, 2017-07-21T17:32:28Z
I want to convert the resulting zoned timestamp to com.google.protobuf.Timestamp but I don´t know how to do that and need help. I am using Kotlin.
So far I´ve tried implementing some of the Java examples from StackOverflow (after converting to Kotlin), for instance:
System.out.println(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXXX")
.format(new Date()));
and
LocalDateTime withoutTimezone = zoneDateTime.toLocalDateTime();
Timestamp timestamp = Timestamp.valueOf(withoutTimezone));
None of the examples seem to work since I need input parameter in com.google.protobuf.Timestamp format, which the above examples do not result in.
Any help would be appreciated regarding how to convert timestamp.

我还没有进行过测试，但从阅读`com.google.protobuf.Timestamp`文档来看，这似乎是一个选项：
String exampleInput = "2020-08-27T20:13:10+02:00";
Instant javaTimeInstant = OffsetDateTime.parse(exampleInput).toInstant();
com.google.protobuf.Timestamp ts = com.google.protobuf.Timestamp.newBuilder()
.setSeconds(javaTimeInstant.getEpochSecond())
.setNanos(javaTimeInstant.getNano())
.build();
我正在使用Java。你可能可以自己将其手动翻译成Kotlin？

I haven’t tested, but from reading the com.google.protobuf.Timestamp documentation this seems to be an option:
String exampleInput = "2020-08-27T20:13:10+02:00";
Instant javaTimeInstant = OffsetDateTime.parse(exampleInput).toInstant();
com.google.protobuf.Timestamp ts = com.google.protobuf.Timestamp.newBuilder()
.setSeconds(javaTimeInstant.getEpochSecond())
.setNanos(javaTimeInstant.getNano())
.build();
I am using Java. You can probably hand translate to Kotlin yourself?
