TTL sets the TTL for a single record only. This will take precedence
|
|
over the domain's [DefaultTTL](../domain/DefaultTTL.md) 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'`?
