Java8 DateTimeFormatter am/pm

Question

I am trying to parse some dates, but the DateTimeParser seems to disagree with me on what is valid

import java.time.ZonedDateTime
import java.time.format.Dat         


        

Answer 1

a expects either PM or AM in upper case. To get a case insensitive formatter you need to build it manually:

DateTimeFormatter fmt = new DateTimeFormatterBuilder()
        .parseCaseInsensitive()
        .appendPattern("EEE MMM dd, yyyy h:mma z")
        .toFormatter(Locale.US);

Note that you will get a new error because the 16th of July is not a Wednesday.
