AmazonマーケットプレイスWebサービス(Amazon MWS) formats date- and time-related data similar to the RFC
3339 standard, which defines a subset profile of ISO 8601 for use in Internet
protocols and standards. This section will clarify just how you should format and
use date and time data in Amazon MWS.
All date and time data is expressed as calendar dates (year, month, day) and a 24-hour day.
Day and time data is always expressed in a combined format. No truncated formats
are allowed. Dates are based on the Gregorian calendar. All date and time data
is expressed numerically, leading zeros are preserved.
The basic type DateTime string patterns are yyyy-MM-ddTHH:mm:ss.sssZ (for
UTC) or yyyy-MM-ddTHH:mm:ss.sss±hh:mm (for a local time
offset). The character 'T' is a required delimiter between the date and
time sections. Times are expressed in the extended format: the ':' is
used as a delimiter between hours, minutes and seconds. Fractional seconds are
expressed with a decimal mark ('.' or ',') when needed.
All use of date and time data in Amazon MWS should be expressed
as type DateTime. However, there are a few parameters that
express date or time as a simple string. Check the parameter type definition to
be sure of which type to use. Using the wrong type will generate an error.
While time intervals and durations are allowed under ISO 8601, they are not currently used in
This example is read as the 16th day of March in 2016 at 14hrs 32min and 16.50 seconds local
time. The local time is 7 hours behind UTC.
