how can I convert a java LocalTime to an Instant in the time zone America/New\_York?

To convert a `LocalTime` to an `Instant` in a specific time zone, you can first create a `ZonedDateTime` object using the `LocalTime`, a date (e.g., the current date), and the desired time zone. Then, you can extract the `Instant` from the `ZonedDateTime`. Here's a code example:

```java
import java.time.*;
import java.time.zone.ZoneId;

public class Main {
    public static void main(String[] args) {
        LocalTime localTime = LocalTime.now(); // Get the current LocalTime
        ZoneId zoneId = ZoneId.of("America/New_York"); // Set the time zone
        ZonedDateTime zonedDateTime = ZonedDateTime.of(LocalDate.now(), localTime, zoneId); // Create a ZonedDateTime
        Instant instant = zonedDateTime.toInstant(); // Convert the ZonedDateTime to an Instant
        System.out.println(instant);
    }
}
```

This code will print the current `Instant` in the "America/New_York" time zone. If you have a specific `LocalTime` and date, you can replace `LocalTime.now()` and `LocalDate.now()` with your desired values.
The following code can be used to convert a LocalTime to an Instant in the time zone America/New York: 

Instant instant = localTime.atZone(ZoneId.of("America/New_York")).toInstant();
