XSLT: Timestamp to epoch v1.0 vs v2.0 -


to convert timestamp epoch in xslt, there suggested method both v1.0 , v2.0 each:

//v2.0 <xsl:value-of select="round((xs:datetime('2017-08-03t19:20:39.096z') - xs:datetime('1970-01-01t00:00:00')) div xs:daytimeduration('pt1s'))"/>

and

//v1.0 <xsl:template name="date-to-unixtime">     <xsl:param name="date"/>      <xsl:variable name="year" select="substring($date, 1, 4)"/>     <xsl:variable name="month" select="substring($date, 6, 2)"/>     <xsl:variable name="day" select="substring($date, 9, 2)"/>      <xsl:variable name="a" select="floor((14 - $month) div 12)"/>     <xsl:variable name="y" select="$year + 4800 - $a"/>     <xsl:variable name="m" select="$month + 12*$a - 3"/>      <xsl:variable name="d" select="$day + floor((153*$m + 2) div 5) + 365*$y + floor($y div 4) - floor($y div 100) + floor($y div 400) - 2472633"/>     <xsl:value-of select="round(86400*$d)" /> </xsl:template>   <xsl:call-template name="date-to-unixtime"><xsl:with-param name="date" select="'2017-08-03t19:20:39.096z'" /></xsl:call-template>       </what></xsl:for-each>

my question is, results of both have difference of 1 min 10 sec. reason be? there way ensure match? interested in because restricted use v1.0. thanks

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
