Description copied from interface: RExpirableReactive

Set an expire date for object in mode. When expire date comes the key will automatically be deleted.

Specified by:

expireAt in interface RExpirableReactive

Parameters:

timestamp - - expire date in milliseconds (Unix timestamp)

Returns:

true if the timeout was set and false if not

expireAt
