Handling TimeZone Conversion in Apex

Before the week ends, here's my next post on handling TimeZone conversion in Apex -

a) Developers might have datetime issue reported before in existing application. This is a good reference for timezone conversion in apex.

b) Another way to retrieve SFDC default timezone  from User object :

Schema.DescribeFieldResult fieldResult = User.TimeZoneSidKey.getdescribe();

List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();

for(Schema.PicklistEntry p : ple){
system.debug('###'+p.getlabel()+'****'+p.getValue()+'\n');
}

Please leave your comment if you agree or have any better approach of handling TimeZone conversion in Apex.
