I know that EXPIREAT in Redis is used to specify when a key will expire. My problem though is that it takes an absolute UNIX timestamp. I'm finding a hard time thinking about what I should set as an argument if I want the key to expire at the end of the day.
This is how I set my key:
If you want to expire it 24 hrs later
client.expireat(key, parseInt((+new Date)/1000) + 86400);
Or if you want it to expire exactly at the end of today, you can use
.setHours on a
new Date() object to get the time at the end of the day, and use that.
var todayEnd = new Date().setHours(23, 59, 59, 999); client.expireat(key, parseInt(todayEnd/1000));
