In Deal Freeze, there are two types of timers: the deal timer and the price-reset timer, as shown in the screenshot below.
Deal timer: the time left until this deal ends. When this timer ends, you will no longer be able to freeze or buy this deal. Deal timer is only displayed if the time left is less than 1 hour.
Price-reset timer: the seconds until the next price fluctuation. This timer is always displayed, and the price will change when it reaches zero.
For more details and guidance, please refer to the official Deal Freeze guide.
