The present invention describes a system, method and computer product program for computation of alarm time. The system includes an alarm device for generating an alarm. The system also includes an alarm application hosted on the alarm device for providing at least one user defined alarm condition. The system further includes an alarm engine for receiving the user defined alarm condition, initiating a probe to receive data from data sources, processing the received alarm conditions and the received data to compute the alarm time and next probe time repeating iteratively until the next probe time is greater than the computed alarm time. The system generates alarm at the computed alarm time when the next probe time becomes greater than the alarm time.
