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
SimpleDateFormatto get aDate, get the milliseconds-since-unix-epoch of that usingDate.getTime(), then compare withSystem.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
Zformat specifier inSimpleDateFormat. (In Java 7 you could useX, but that’s not available in Android’s version ofSimpleDateFormatas far as I’m aware.)
