Usage

The Clock component displays a clock with customizable hands, ticks, and numbers.

import { Clock } from '@gfazioli/mantine-clock';

function Demo() {
  return (

  );
}

The Clock component can display a static time using the value prop. When running is set to false, the clock will show the specified time without animation. If no value is provided, it displays the current time. The value prop accepts time strings in various formats or Date objects.

Reverse Countdown Clock

This demo showcases how to create a reverse countdown clock by combining the Clock component with the useClockCountDown hook. The clock displays the remaining time visually as it counts down, creating a unique reverse clock effect. The clock hands move backwards as time decreases, and the appearance changes when the countdown is completed.

import { Clock } from '@gfazioli/mantine-clock';

function Demo() {
  return (
    <Clock secondHandColor="" minuteHandColor="" hourHandColor="" />
  );
}

Clock Numbers

The Clock component can display numbers on the clock face. You can customize the font size, color, and visibility of the numbers.

Secondary numbers color

Secondary numbers opacity

import { Clock } from '@gfazioli/mantine-clock';

function Demo() {
  return (
    <Clock primaryNumbersColor="" secondaryNumbersColor="" />
  );
}

Clock Number Fonts

The Clock component supports custom fonts for the numbers displayed on the clock face. You can choose from various font styles to match your design preferences.

import { Clock } from '@gfazioli/mantine-clock';

function Demo() {
  return (
    <Clock
      primaryNumbersColor="blue"
      primaryNumbersProps={{
        ff: 'monospace',
        fw: 900,
        fz: 32,
      }}
      secondaryNumbersColor="gray"
      secondaryNumbersProps={{
        ff: 'monospace',
        fw: 500,
        fz: 16,
      }}
      styles={{
        primaryNumber: {
          textShadow: '0 4px 6px rgba(0, 0, 0, 0.3)',
        },
      }}
    />
  );
}

Styling with ClassNames

The Clock component supports extensive customization through the classNames prop, allowing you to style every part of the clock using CSS modules or custom CSS classes. This approach gives you complete control over the clock's appearance.

Available ClassNames

The Clock component exposes the following classNames for styling:

root - Root element of the clock component
clockContainer - Main clock container
glassWrapper - Glass wrapper with shadow effects
clockFace - Clock face containing all visual elements
hourMarks - Container for hour marks and numbers
hourTick - Hour tick marks (12 positions)
minuteTick - Minute tick marks (60 positions, excluding hour positions)
number - Base styles for hour numbers (1-12)
primaryNumber - Primary hour numbers (12, 3, 6, 9)
secondaryNumber - Secondary hour numbers (1, 2, 4, 5, 7, 8, 10, 11)
hand - Base styles for clock hands
hourHand - Hour hand specific styles
minuteHand - Minute hand specific styles
secondHandContainer - Container for second hand and counterweight
secondHand - Second hand specific styles
secondHandCounterweight - Second hand counterweight
centerBlur - Center blur effect
centerDot - Center dot at the pivot point

Neon Theme Example

The following example demonstrates a complete custom theme using CSS modules with neon effects, animations, and modern styling techniques:

Neon Cyber Clock Theme

Custom styling using CSS modules and classNames prop

import { Clock } from '@gfazioli/mantine-clock';
import { Stack, Text, Title } from '@mantine/core';
import classes from './Clock.demo.classNames.module.css';

function Demo() {
  return (
    <Stack align="center" justify="center">
      <Title order={4} ta="center" mb="xs">
        Neon Cyber Clock Theme
      </Title>
      <Text size="sm" c="dimmed" ta="center" mb="md">
        Custom styling using CSS modules and classNames prop
      </Text>
      <Clock
        size={200}
        secondHandBehavior="smooth"
        classNames={{
          glassWrapper: classes.glassWrapper,
          clockFace: classes.clockFace,
          hourTick: classes.hourTick,
          minuteTick: classes.minuteTick,
          primaryNumber: classes.primaryNumber,
          secondaryNumber: classes.secondaryNumber,
          hourHand: classes.hourHand,
          minuteHand: classes.minuteHand,
          secondHand: classes.secondHand,
          secondHandCounterweight: classes.secondHandCounterweight,
          centerDot: classes.centerDot,
          centerBlur: classes.centerBlur,
        }}
      />
    </Stack>
  );
}

Timezone Support

The Clock component supports displaying time in different timezones around the world. Use the timezone prop to specify a timezone string, allowing you to create world clocks or display time for specific regions.

Timezone

import { Clock } from '@gfazioli/mantine-clock';

function Demo() {
  return (
    <Clock timezone="UTC" />
  );
}

World Clocks Example

Here's an example showing multiple clocks displaying time in different regions simultaneously:

New York

London

Tokyo

import { Clock } from '@gfazioli/mantine-clock';
import { Group, Stack, Text } from '@mantine/core';

// This demo showcases the usage of the Clock component from the @gfazioli/mantine-clock package.
// It displays world clocks for different timezones, allowing users to see the current time in various locations.

function Demo() {
  return (
    <Group grow>
      <Stack align="center">
        <Clock timezone="America/New_York" size={200} />
        <Text fw={600} c="dimmed">
          New York
        </Text>
      </Stack>

      <Stack align="center">
        <Clock timezone="Europe/London" size={200} />
        <Text fw={600} c="dimmed">
          London
        </Text>
      </Stack>

      <Stack align="center">
        <Clock timezone="Asia/Tokyo" size={200} />
        <Text fw={600} c="dimmed">
          Tokyo
        </Text>
      </Stack>
    </Group>
  );
}

Supported Timezones

The timezone prop accepts any valid IANA timezone identifier. Some common examples include:

UTC: 'UTC' - Coordinated Universal Time
Americas: 'America/New_York', 'America/Los_Angeles', 'America/Chicago', 'America/Toronto'
Europe: 'Europe/London', 'Europe/Berlin', 'Europe/Paris', 'Europe/Rome'
Asia: 'Asia/Tokyo', 'Asia/Shanghai', 'Asia/Singapore', 'Asia/Dubai'
Oceania: 'Australia/Sydney', 'Australia/Melbourne', 'Pacific/Auckland'

When no timezone is specified, the clock displays the local time of the user's system.

Usage Examples

import { Clock } from '@gfazioli/mantine-clock';

function Demo() {
  return (
    <div>
      {/* Display Tokyo time */}
      <Clock timezone="Asia/Tokyo" />

      {/* Display New York time */}
      <Clock timezone="America/New_York" />

      {/* Display UTC time */}
      <Clock timezone="UTC" />

      {/* Display local time (default) */}
      <Clock />
    </div>
  );
}

Hooks

useClock Hook

The useClock hook provides real-time clock data with support for timezones, formatting options, and update frequency control. This hook is perfect for creating digital clocks, displaying time information, or building custom time-based components.
