Summary: IntlDateFormatter::parse result is limited to the
integer range
Status: Assigned
Type: Bug

New Comment:
Actually what I want to do is to convert dates between different
calendars and to do so I'm using the returned timestamp with
IntlDateFormatter::format method as follow:
$df_persian = new IntlDateFormatter('e...@calendar=persian',
IntlDateFormatter::FULL, IntlDateFormatter::FULL, 'Asia/Tehran',
IntlDateFormatter::GREGORIAN, 'yyyy-MM-dd');
$df_gregorian = new IntlDateFormatter('en', IntlDateFormatter::FULL,
IntlDateFormatter::FULL, 'Asia/Tehran', IntlDateFormatter::GREGORIAN,
'yyyy-MM-dd');
echo $df_gregorian->format($df_persian->parse('1388-03-31'));
Hopefully, format method accepts float values as argument and the only
problem is parse method which doesn't return past-2038 timestamps.
And by the way float precision loss wouldn't be a problem at least for
timestamps up to 14 decimal digits.

Out of curiosity - how do you expect to use past-2038 timestamps? Many
Unix systems won't support those. Do you expect 64-bit value or some
other way? float might be not very good for it due to the precision
loss.

Description:
------------
The result of IntlDateFormatter::parse is integer and is limited to the
integer range. (i.e. IntlDateFormatter::parse returns The least integer
value (e.g. -2147483648 in 32-bit Platforms) when the result is out of
the integer range.)
Reproduce code:
---------------
$fmt = new IntlDateFormatter("en_US", IntlDateFormatter::FULL,
IntlDateFormatter::FULL);
var_dump($fmt->parse("Wednesday, January 20, 2038 3:14:07 AM GMT"));
Expected result:
----------------
float(2147570047)
Actual result:
--------------
int(-2147483648)
