Hi russel,
Thanks for your reply, much appreciated..

If I can change the date/time format to a format where it is only one
string
what will be java syntax for definign the option within my application

e.g
inal Option persistDataOption =
 OptionBuilder.withArgName("persist").hasOptionalArgs(3)
 hasArg().withDescription("Persist Data with Scheduling") 
 .create("-p");

I cant seem to get the above line correct...

I want to define an option that has
A. 3 options... name> | <Time> | <Boolean
B. 1 Mandatory ... name
C. 2 optional params Time , Boolean

Can you help me define this option correctly first, then I can move on
and
worry about the  Date/Time being 2 strings

Regards
jhon

I don't have an immediate answer for you I'm afraid.  The reason for
replying is to note that this looks almost, but not quite exactly, like
an ISO 8601 date -- the differences are going to be very irritating I
suspect.  The though struck me that ISO 8601 date should be a known
construct to any CLI system.  Of course, Java's current date system is
effectively rubbish, and JodaTime isn't yet standard.

I suspect the only way forward for the moment is to quote the date
string as a parameter or use the full no space ISO 8601 format (i.e.
replace space with T), and then ship the string to a JodaTime function
for parsing.
