I’m currently reviewing/reversing a software (coded in C) and it has a line like this :
time_t var = time(0);
My goal it to get this time(0) call to return -1.
(I cannot modify the parameter.)
Looking for any hints/POC methods to achieve … Continue reading Making time(0) produce an error
I am working on a project where I have to calculate the encryption time and decryption time of an algorithm. How to calculate encryption, decryption and key generation time of an algorithm? Is there any formula to calculate these?

There are a lot of apps and websites that can not be accessed without setting the correct time zone. Windows is well aware of this perk and has included an option to set the time zone automatically. However, according to some reports, the Set time zone… Continue reading Set time zone automatically greyed out in Windows 11
Physicists at the University of Oxford have successfully linked two atomic clocks through quantum entanglement for the first time. The feat can help make these clocks so precise that they begin to approach the fundamental limit of precision set by quan… Continue reading Oxford physicists create network of quantum-entangled atomic clocks
I’m addicted to this game, and while I don’t want to delete it, I want to be able to encrypt/lock it in a way where the decrypting/unlocking takes a day, and ideally during that day I can cancel the decryption process (hopefully by that ti… Continue reading How to encrypt a file that only "unlocks" after a day?
The best time of day to exercise is a long-standing question, and now a new study suggests that it differs by sex. The team found that evening exercise was more effective for men than morning routines, while results for women varied, with different hea… Continue reading Best time of day to exercise seems to be different for men and women
Network Time Protocol (NTP) is one of the best ways to keep networked computers synchronized to the same time. It’s simple, lightweight, and not only allows computers to maintain a …read more Continue reading Network Time Protocol on the ESP32
The movements of the Sun, Moon and stars have long been used to keep track of time, and now engineers from the University of Tokyo have proposed a new way to use the cosmos to precisely track time, using showers of particles from cosmic rays.Continue R… Continue reading Cosmic timekeeping tech works underground or underwater
Britain’s supercarrier HMS Prince of Wales has become the first surface ship to be equipped with a state-of-the-art atomic clock as it departs for the Exercise Cold Response 2022 NATO joint exercises off the north coast of Norway.Continue ReadingCatego… Continue reading HMS Prince of Wales becomes first surface ship to carry an atomic clock
The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at different speeds across just one millimeter, the smallest d… Continue reading Physicists measure gravitational time warp to within one millimeter
