HammerTime

Input settings

Custom date input

Replace the browser default date input with a custom one.

Custom time input

Replace the browser default time input with a custom one. This is especially useful if you have trouble selecting the time on mobile browsers.

Separate inputs

Display two different inputs for date and time instead of a combined one (which is not supported in some browsers)

@time input field

Allow manipulating the selected timestamp with natural language (e.g. “in 5 hours”) via an additional free-text input. Similar to the new Discord @time tag. Only a limited number of languages are supported.

Flatten interface

Disable shadow and height effects on inputs and buttons

Custom time input clock type

Change how hours should be displayed in the custom time input. Has no effect on the previews in the example results column.

First day of the week

Change which day should be considered the first day of the week in the calendar of the custom date input.

Time Synchronization

Your system clock is currently being synchronized with our servers, please wait.

t₀0 ms t₁0 ms t₂0 ms t₃

Active Calculation Offset	0 ms
Detected Offset (via Network)	NaN ms
Round-trip duration	0 ms

Apply server time offset to calculations (beta)

If your system clock is over 300000 ms off compared to the server time (excluding timezone differences), some time calculations will be adjusted to take this into account, so your timestamps will be less likely to be incorrect. This is an experimental feature, use with caution! Synchronization happens when the page is first loaded, and immediately after the setting is turned on.
