1. An electronic time warhead (EOT) fuze for a hand grenade, comprising:
a body;
a clamp with two terminals keeping a spring and a handle in an armed position;
the handle keeping the spring in the armed position while the user wields the hand grenade;
the spring being housed in a spring pin, wherein the spring initializes the EOT which, when the hand grenade is thrown, seeks a rest position by expelling the handle and activating a switch energizing an electronic circuit;
a battery electrically connected to the electronic circuit; and
an initiator element, wherein the initiator element consists of a conductive filament impregnated with a chemical mixture generating an initiating flame from the electrical signal applied by the electronic circuit.
