Generate random Unix timestamps in Ruby using Time.now and rand(). Covers current time, past/future timestamps, and formatting for Rails testing. Looking for other languages? Check our code examples in PHP , JavaScript , Python , Java , C# , C++ and Go or use our interactive web generator.

Ruby Code Example

require "time"

# Generate current Unix timestamp
def current_timestamp
  Time.now.to_i
end

# Generate random timestamp between two dates
def random_timestamp(start_date, end_date)
  start_time = Time.parse(start_date).to_i
  end_time = Time.parse(end_date).to_i
  rand(start_time..end_time)
end

# Generate random past timestamp (within N days)
def random_past_timestamp(days_ago = 365)
  now = Time.now.to_i
  seconds = days_ago * 86400
  rand((now - seconds)..now)
end

# Generate random future timestamp (within N days)
def random_future_timestamp(days_ahead = 365)
  now = Time.now.to_i
  seconds = days_ahead * 86400
  rand(now..(now + seconds))
end

# Convert timestamp to readable format
def format_timestamp(timestamp, format = "%Y-%m-%d %H:%M:%S")
  Time.at(timestamp).strftime(format)
end

# Generate multiple random timestamps
def generate_timestamps(count = 10, start_date = "2020-01-01", end_date = "2024-12-31")
  Array.new(count) { random_timestamp(start_date, end_date) }
end

puts "Current: #{current_timestamp}"
puts "Random: #{random_timestamp(\"2023-01-01\", \"2024-12-31\")}"
past = random_past_timestamp(30)
puts "Past: #{past} (#{format_timestamp(past)})"
future = random_future_timestamp(30)
puts "Future: #{future} (#{format_timestamp(future)})"
puts "Batch: #{generate_timestamps(3).join(\", \")}\"

[EXPLANATION]

Ruby Time.now.to_i returns current Unix timestamp (seconds). Time.parse() parses date strings to Time objects. rand(start..end) generates random integers in range. Time.at() converts timestamp to Time object. strftime() formats for display. 86400 is seconds per day. Use Time.utc() instead of Time.now for UTC timestamps.

Expected Output

Current: 1703001234
Random: 1698765432
Past: 1700445678 (2023-11-19 14:27:58)
Future: 1706123456 (2024-01-24 18:10:56)
Batch: 1680123456, 1685432100, 1692345678
