TTL sets the TTL for a single record only. This will take precedence over the domain's DefaultTTL if supplied.
The value can be:
  • An integer (number of seconds). Example: 600
  • A string: Integer with single-letter unit: Example: 5m
  • The unit denotes:
    • s (seconds)
    • m (minutes)
    • h (hours)
    • d (days)
    • w (weeks)
    • n (nonths) (30 days in a nonth)
    • y (years) (If you set a TTL to a year, we assume you also do crossword puzzles in pen. Show off!)
    • If no unit is specified, the default is seconds.
  • We highly recommend using units instead of the number of seconds. Would your coworkers understand your intention better if you wrote 14400 or '4h'?
