time.gmtime() causes OverflowError on armhf platform <p>I have a webserver (CherryPy) running with on a Cubox (armhf platform) and upon starting the wever i get the following error:</p> <pre><code>[14/Aug/2015:09:33:40] HTTP Traceback (most recent call last): File "(...)/lib/python3.4/site-packages/cherrypy/_cprequest.py", line 661, in respond self.hooks.run('before_request_body') File "(...)/lib/python3.4/site-packages/cherrypy/_cprequest.py", line 114, in run raise exc File "(...)/lib/python3.4/site-packages/cherrypy/_cprequest.py", line 104, in run hook() File "(...)/lib/python3.4/site-packages/cherrypy/_cprequest.py", line 63, in __call__ return self.callback(**self.kwargs) File "(...)/lib/python3.4/site-packages/cherrypy/lib/sessions.py", line 901, in init httponly=httponly) File "(...)/lib/python3.4/site-packages/cherrypy/lib/sessions.py", line 951, in set_response_cookie cookie[name]['expires'] = httputil.HTTPDate(e) File "(...)/lib/python3.4/site-packages/cherrypy/_cpcompat.py", line 278, in HTTPDate return formatdate(timeval, usegmt=True) File "/usr/lib/python3.4/email/utils.py", line 177, in formatdate now = time.gmtime(timeval) OverflowError: timestamp out of range for platform time_t </code></pre> <p>I'm not sure whether I understand the problem correctly and I am not sure if it can be fixed by me. As far as I can tell by the Traceback it is caused by CherryPy. This error causes a <code>500 Internal Server Error</code> and won't load the page.</p> <p>As asked in the comments I inserted a print. I don't see any thing special. This is the output of starting the server and once trying to load the page:</p> <pre><code>1439551125.1483066 1439551132.639804 4593151132.6458025 1439551132.723468 1439551132.7210276 1439551132.7268708 1439551132.7359934 1439551132.741787 1439551132.7452564 4593151132.750907 4593151132.762612 4593151132.749376 4593151132.731232 4593151132.754474 4593151132.763546 1439551132.8183882 4593151132.828029 1439551132.8379567 4593151132.856025 1439551132.8734775 1439551132.8554301 1439551132.879614 4593151132.884698 4593151132.890394 1439551132.8971672 4593151132.902081 4593151132.908171 1439551132.931757 4593151132.944052 1439551132.9759347 1439551132.9714596 4593151132.987068 4593151132.985899 1439551132.9926524 1439551133.0088623 4593151133.013047 1439551133.0280995 4593151133.040709 4593151133.029601 1439551133.0500746 4593151133.057341 1439551133.0749385 4593151133.081711 1439551133.1032782 4593151133.115171 1439551133.1194305 1439551133.1354048 4593151133.143136 4593151133.151044 1439551133.1612003 4593151133.16934 1439551133.1827784 4593151133.19687 1439551133.201899 4593151133.209947 1439551133.271833 4593151133.277573 1439551133.3090906 4593151133.312978 1439551133.3408027 4593151133.344741 1439551133.3722978 4593151133.376283 1439551133.4031894 4593151133.407124 1439551133.434834 4593151133.439074 </code></pre> <p>I am not sure which of these values causes the error. I am guessing it's the one with 4 in front? On a windows machine <code>time.gmtime(4593151133.439074)</code> returns a struct which contains the year 2115.</p> <p>On the Cubox when starting a python shell and entering <code>time.gmtime(4593151133.439074)</code> I can reproduce the error. But I don't know where these values come from. </p> <p><strong>EDIT</strong></p> <p>I have found the file and line in CherryPy that returns me the floating numbers which lead to the year 2115. It is line 949 - 951 in the file session.py: </p> <pre><code>if timeout: e = time.time() + (timeout * 60) cookie[name]['expires'] = httputil.HTTPDate(e) </code></pre> <p>Why I get such a high timeout, I don't know.</p>
