why not to log a call through a customized URL bookmarked in your favorite browser?

so i starting to search, thanks the firefox extension firebug by the way, and here is the result of my search:

https://crm.zoho.com/crm/Create.do?module=Events&isload=true&property(Subject)=Call&property(Start DateTime)=23/10/2007&property(Start DateTimehour)=09&property(Start DateTimeminute)=00&property(Start DateTimeampm)=PM&property(End DateTime)=23/10/2007&property(End DateTimehour)=09&property(End DateTimeminute)=30&property(End DateTimeampm)=PM

with this URL you can log an event with subject "call" and a start date 23/10/2007 with time 09:00 PM end date 23/10/2007 and time 09:30 PM

now = new Date();
today = now.getDate() + "/" + (now.getMonth()+1) + "/" + now.getFullYear();
ampm = "AM"
if(now.getHours()>12){ampm = "PM"};
hours = now.getHours() % 12;
minutes = now.getMinutes();

location="https://crm.zoho.com/crm/Create.do?module=Events&isload=true&property(Subject)=Call&property(Start DateTime)=" + today + "&property(Start DateTimehour)=" + hours + "&property(Start DateTimeminute)=" + minutes + "&property(Start DateTimeampm)=" + ampm + "&property(End DateTime)=" + today + "&property(End DateTimehour)=" + hours + "&property(End DateTimeminute)=" + minutes + "&property(End DateTimeampm)=" + ampm
