The following table contains information about the data types used in the web services (except where the data type format is obvious).

Data Type	Discussion
boolean	The possible values are the strings true and false.
date	The date format is yyyy-mm-dd. For example, 2004-12-26.
dateTime	The dateTime format is yyyy-mm-ddThhMMss.fffffff<tzadjustment>, where the T must be present between the date and time, and both the .fffffff (fraction of a second) and <tzadjustment> are optional. Note that the time is GMT, and the adjustment shows the hours relative to GMT. For our servers that is currently -05:00 hours, but could change if the change the timezone setting of our servers. Examples: 2004-12-27T11:04:29.4370000-05:00 2004-12-27T06:04:29.4370000 2004-12-27T11:04:29-05:00 2004-12-27T10:04:29 The first two and last two examples represent the same time.
int	A signed integer internally represented by 32 bits
long	A signed integer internally represented by 64 bits
money	A decimal number with 4 places to the right of the decimal point.
float	A floating point number (internally represented by 4 bytes)
double	A double precision floating point number (internally 8 bytes)
