r2485 r2488 213 213 </artwork></figure> 214 214 <t> 215 A recipient parsing a deltaseconds value ought to use an arithmetic type 216 of at least 32 bits of signed integer range. A sender &MUSTNOT; generate a 217 deltaseconds value greater than 2147483647 (32bit INT_MAX, or 218 2<x:sup>31</x:sup>  1). 219 </t> 220 <t> 215 221 If a cache receives a deltaseconds value larger than the largest 216 222 positive integer it can represent, or if any of its subsequent calculations 217 overflows, the cache &MUST; consider the value to be 2147483648 218 (2<x:sup>31</x:sup>). A recipient parsing a deltaseconds value &MUST; use 219 an arithmetic type of at least 31 bits of range, and a sender &MUSTNOT; 220 generate deltaseconds with a value greater than 2147483648. 221 </t> 222 <t> 223 Note that this value (2147483648) might cause implementation issues on some 224 platforms (in particular, those that represent MAX_INT as 225 2<x:sup>31</x:sup>1), and therefore ought to be handled carefullly. 223 overflows, the cache &MUST; consider the value to be the largest positive 224 integer it can represent. 226 225 </t> 227 226 </section>
