Time Seed (JPS)

Documentation

• Class name: Time Seed (JPS)
• Category: JPS Nodes/Text
• Output node: False

The Time Seed node generates a unique seed value based on the current time, optionally allowing for a fixed seed to be specified. This functionality is crucial for ensuring reproducibility in processes that require randomization, by providing a way to initialize random number generators with a consistent starting point.

Input types

Required

• fixed_seed
  • Specifies a fixed seed value to be used instead of generating one based on the current time. If set to 0, a time-based seed is generated, ensuring variability with each execution.
  • Comfy dtype: INT
  • Python dtype: int

Output types

• seed
  • Comfy dtype: INT
  • The generated seed value, which is either based on the current time or the specified fixed seed, used for initializing random number generators.
  • Python dtype: int

Usage tips

• Infra type: CPU
• Common nodes: unknown
