0xE7791F700
Dear fellow reverser,
I'm creating this Gist in the hopes that it will be indexed and that people who look up this value: 0xE7791F700 will end up here.
62135596800 is the number of seconds that separate the Go Epoch from the Unix epoch. You're probably looking at an inlined call like `time.Now().Unix()`.
Cheers,
@JusticeRage
