Is the Joda-Time DateTimeFormatter class thread safe? Once I get an instance from DateTimeFormat.forPattern, can its various parse methods be called by multiple threads? DateTimeFormatter's Javadocs makes no mention of thread safety.

A pattern is used to create a Formatter using the ofPattern(String) and ofPattern(String, Locale) methods. For example, "d MMM uuuu" will format 2011-12-03 as '3 Dec 2011'. A formatter created from a pattern can be used as many times as necessary, it is immutable and is thread-safe.
DateTimeFormatter is immutable and thread-safe. DateTimeFormatter formats a date-time using user defined format such as "yyyy-MMM-dd hh:mm:ss" or using predefined constants such as ISO_LOCAL_DATE_TIME. A DateTimeFormatter can be created with desired Locale, Chronology, ZoneId, and DecimalStyle.
How to change the SimpleDateFormat to jodatime? String s = "2014-01-15T14:23:50.026"; DateTimeFormatter dtf = DateTimeFormat. forPattern("yyyy-MM-dd'T'HH:mm:ss. SSSS"); DateTime instant = dtf.
Yes, it is:
DateTimeFormat is thread-safe and immutable, and the formatters it returns are as well.
and so is the Java 8 version
Implementation Requirements: This class is immutable and thread-safe.
