var time = require( '@stdlib/time' );
```
#### time
Namespace containing time utilities.
```javascript
var ns = time;
// returns {...}
```
### Calendar Utilities
- [`dayOfQuarter( [month[, day, year]] )`][@stdlib/time/day-of-quarter]: determine the day of the quarter.
- [`dayOfYear( [month[, day, year]] )`][@stdlib/time/day-of-year]: determine the day of the year.
- [`daysInMonth( [month[, year]] )`][@stdlib/time/days-in-month]: determine the number of days in a month.
- [`daysInYear( [value] )`][@stdlib/time/days-in-year]: determine the number of days in a year according to the Gregorian calendar.
- [`hoursInMonth( [month[, year]] )`][@stdlib/time/hours-in-month]: determine the number of hours in a month.
- [`hoursInYear( [value] )`][@stdlib/time/hours-in-year]: determine the number of hours in a year according to the Gregorian calendar.
- [`isoWeeksInYear( [value] )`][@stdlib/time/iso-weeks-in-year]: determine the number of ISO weeks in a year according to the Gregorian calendar.
- [`minutesInMonth( [month[, year]] )`][@stdlib/time/minutes-in-month]: determine the number of minutes in a month.
- [`minutesInYear( [value] )`][@stdlib/time/minutes-in-year]: determine the number of minutes in a year according to the Gregorian calendar.
- [`quarterOfYear( [month] )`][@stdlib/time/quarter-of-year]: determine the quarter of the year.
- [`secondsInMonth( [month[, year]] )`][@stdlib/time/seconds-in-month]: determine the number of seconds in a month.
- [`secondsInYear( [value] )`][@stdlib/time/seconds-in-year]: determine the number of seconds in a year according to the Gregorian calendar.
```javascript
var num = time.daysInYear( 2000 );
// returns 366
num = time.hoursInMonth( 2, 2017 );
// returns 672
```
### Timer Utilities
- [`tic()`][@stdlib/time/tic]: return a high-resolution time.
- [`toc( time )`][@stdlib/time/toc]: return a high-resolution time difference.
```javascript
var time = require( '@stdlib/time' );
var start = time.tic();
setTimeout( onTimeout, 2000 );
function onTimeout() {
var elapsed = time.toc( start );
console.log( 'Elapsed: %d seconds and %d nanoseconds', elapsed[0], elapsed[1] );
}
```
