1. A ballistic transfer delay device, the device comprising: a time delay fuse;a through-bulkhead initiator to initiate the time delay fuse, wherein the time delay fuse, the through-bulkhead initiator, and the output booster do not comprise a moving element; andan output booster to ballistically transfer the energy from the initiated time delay fuse. 2. The device of claim 1, wherein the output booster is a deflagration to detonation initiator. 3. The device of claim 1, wherein the through-bulkhead initiator is not pressure activated. 4. The device of claim 1, wherein the through-bulkhead initiator is ballistically initiated. 5. The device of claim 1, wherein the output booster is a deflagration to detonation initiator. 6. The device of claim 1, wherein the through-bulkhead initiator is not pressure activated. 7. A wellbore apparatus, the apparatus comprising: a firing head;a first and a second explosive device connected to the firing head within a ballistic train; anda ballistic transfer delay device connected within the ballistic train between the first explosive device and the second explosive device, wherein the ballistic transfer delay device comprises a time delay fuse, a through-bulkhead initiator to initiate the time delay fuse, and an output booster to ballistically transfer the energy from the initiated time delay fuse to the second explosive device, wherein the ballistic transfer delay device does not comprise a moving part. 8. The apparatus of claim 7, wherein the first and the second explosive devices are perforating guns. 9. The apparatus of claim 7, wherein the first explosive device comprises a detonation cord, an explosive charge connected to the detonation cord, and an output booster to ballistically transfer the detonation from the detonation cord to the through-bulk initiator. 10. The apparatus of claim 7, wherein the ballistic transfer delay device does not comprise a firing pin. 11. The apparatus of claim 7, the ballistic transfer delay device is not pressure initiated. 12. The apparatus of claim 7, wherein the output booster is a deflagration to detonation initiator. 13. The apparatus of claim 7, wherein: the ballistic transfer delay device does not comprise a firing pin;andthe through-bulkhead initiator is not pressure initiated. 14. The apparatus of claim 13, wherein the first explosive device comprises a detonation cord, an explosive charge connected to the detonation cord, and an output booster to ballistically transfer the detonation from the detonation cord to the through-bulk initiator. 15. A method for perforating, comprising: conveying a perforating apparatus to a position adjacent to a first zone in a wellbore, the perforating apparatus comprising a firing head, a first perforating gun and a second perforating gun connected to the firing head within a ballistic train, and a ballistic transfer delay device connected within the ballistic train between the first perforating gun and the second perforating gun, wherein the ballistic transfer delay device comprises a time delay fuse, a through-bulkhead initiator, and an output booster, wherein the ballistic transfer delay device does not comprise a moving part;detonating the first perforating gun in response to initiating the firing head;initiating the through-bulkhead initiator in response to ballistically transferring the detonation from the first gun to the through-bulkhead initiator;igniting the time delay fuse in response to initiating the through-bulkhead initiator;positioning the perforating apparatus adjacent to a second zone in the wellbore during a ballistic time delay associated with the ignited time delay fuse; anddetonating the second perforating gun in response to ballistically transferring the energy from the time delay fuse to the second perforating gun. 16. The method of claim 15, wherein: the ballistic transfer delay device does not comprise a firing pin;andthe through-bulkhead initiator is not pressure initiated. 17. The method of claim 15, wherein: the first perforating gun comprises a detonation cord, an explosive charge connected to the detonation cord, and an output booster; andthe ballistically transferring the detonation from the first gun to the through-bulkhead initiator comprises transferring the detonation from the output booster to an input booster of the through-bulkhead initiator.
