Where not explicitly specified otherwise, date/time values are returned in ISO format, e.g.: 2011-12-03T10:15:30.123. Where only the date component is present, it will be returned as 2011-12-03 and where only the time component is present only the time part, 10:15:30.123, will be returned.
Timezone
All input and output date/times are assumed to be in UTC timezone. Where required, the calling appliations need to localise the date/time to user-specific timezones.
