When I am running the below code to convert the time string to Java date, it is failing.
String s = "04/17/2017 06:46:53 -600";
SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss Z");
Date value = format.parse(s);
Exception in thread "main" java.text.ParseException: Unparseable date: "04/17/2017 06:46:53 -600"
at java.text.DateFormat.parse(Unknown Source)
What is the correct format string to be used to convert the date string to java date ?
add -0600 instead -600 read link
import java.text.*;
import java.util.*;
class TestFormatDate {
public static void main(String arg[]) throws Exception{
String s = "04/17/2017 06:46:53 -0600";
SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss Z");
Date value = format.parse(s);
System.out.println("value "+value);
}
}
As the SimpleDateFormat time zone documentation explain :
RFC 822 time zone: For formatting, the RFC 822 4-digit time zone format is used:
RFC822TimeZone:
Sign TwoDigitHours Minutes
TwoDigitHours:
Digit Digit
ISO 8601 Time zone: The number of pattern letters designates the format for both formatting and parsing as follows:
ISO8601TimeZone:
OneLetterISO8601TimeZone
TwoLetterISO8601TimeZone
ThreeLetterISO8601TimeZone
OneLetterISO8601TimeZone:
Sign TwoDigitHours
Z
TwoLetterISO8601TimeZone:
Sign TwoDigitHours Minutes
Z
ThreeLetterISO8601TimeZone:
Sign TwoDigitHours : Minutes
Z
Hours is always seen with two digits so you need to pass -0600 as a timezone or -06
The only way you can have a one digit hours is with :
General time zone: Time zones are interpreted as text if they have names. For time zones representing a GMT offset value, the following syntax is used:
GMTOffsetTimeZone:
GMT Sign Hours : Minutes
Sign: one of
+ -
Hours:
Digit
Digit Digit
Minutes:
Digit Digit
Digit: one of
0 1 2 3 4 5 6 7 8 9
-0600not-600
