jodatime - Last milliseconds of a day in ISO format in Java -

i have string representations of dates need convert date objects. need start of day , end of day in datetime down millisecond. here have far:

date format is:

yyyy-mm-dd't'hh:mm:ss.sss'z' 

start of day:

2013-05-19t00:00:00+00:00 

end of day:

2013-05-19t23:59:59+59:59 

the 'start of day' parses ok 'end of day' throws

java.lang.illegalargumentexception: invalid format: "2013-05-19t23:59:59+59:59" malformed @ "59:59" 

the bit after + isn't milliseconds. + introduces timezone offset. +00:00 gmt (greenwich mean time). +01:00 hour later (cet; central european time).

for last millisecond of day, want:

2013-05-19t23:59:59.999 milliseconds -------^^^

note that's . before 999, because we're writing there 59.999 seconds.

if want to, can add timezone indicator on that, e.g.:

2013-05-19t23:59:59.999+00:00

more iso-8601.
