Android/Java Time difference ISO 8601 with Now

Question

I have an ISO 8601 time string and want to calculate the time difference to now in minutes without using joda time. How is this done?

Thanks

Parse it using SimpleDateFormat to get a Date, get the milliseconds-since-unix-epoch of that using Date.getTime(), then compare with System.currentTimeMillis().

If your ISO-8601 strings contain a time zone offset as something like "-08:00" (which they certainly can), you'll need to remove the colon first, and use the Z format specifier in SimpleDateFormat. (In Java 7 you could use X, but that's not available in Android's version of SimpleDateFormat as far as I'm aware.)

Note that I had to drop the "Z" in the SimpleDateFormat format for things to work. — mraviator, Mar 16 '12 at 13:15

What about javax.xml.datatype.Duration as returned by javax.xml.datatype.DatatypeFactory?

I ended up copying the file org/apache/axis/types/Duration.java, with a few modifications. – Sofi Software LLC Aug 02 '12 at 23:06
