DateTime values are expected to be in the ISO 8601 format, for example '2013-02-14T13:15:03-08:00' (YYYY-MM-DDTHH:mm:ssZ).
Below are examples for generating ISO 8601 datetime strings in a few popular programing languages.
Java
Date
date
=
new
Date
();
DateFormat
df
=
new
SimpleDateFormat
(
"yyyy-MM-dd'T'HH:mm:ssZ"
);
String
dateAsISOString
=
df
.
format
(
date
);
JavaScript
var
d
=
new
Date
();
var
date
=
d
.
toISOString
();
PHP
$objDateTime = new DateTime('NOW');
$isoDate = $objDateTime->format(DateTime::ISO8601);
Python
from
datetime
import
date
d
=
date
.
now
()
date
=
d
.
isoformat
()
Ruby
require
'time'
d
=
Time
.
now
date
=
d
.
utc
.
iso8601
Perl
my
$now
=
time
();
$date
=
time2isoz
(
$now
);
C++
time_t
now
;
time
(
& now
);
char
buf
[
sizeof
"2011-10-08T07:07:09Z"
];
strftime
(
buf
,
sizeof
buf
,
"%FT%TZ"
,
gmtime
(
& now
));
