comment How to figure out the seed I used to generate several random numbers given that I didn't used SeedRandom at first place?
SeedRandom[n] does not use the time. SeedRandom[] uses system clock plus some unspecified system attributes. From what I understand, you did not use SeedRandom, so we cannot know what state the pseudo-random generator was in.
