TimeAdd

This reference topic applies to FQL v4. Go to this page for the latest FQL v10 reference topics.

 
TimeAdd( base, offset, unit )
time_add( base, offset, unit )
TimeAdd( base, offset, unit )
TimeAdd( base, offset, unit )
TimeAdd( base, offset, unit )
TimeAdd( base, offset, unit )

Description

The TimeAdd function increases a base Timestamp or Date by adding the offset in units.

Parameters

Parameter Type Definition and Requirements

base

Timestamp or Date

A timestamp or date to add to. base must match the type of unit.

offset

Integer or Long

The integer number of units to add to base.

unit

String

Unit of the offset.

When base is a Date, unit must be one of day or days.

When base is a Timestamp, unit must be one of:

  • day, or days

  • half day, or half days

  • hour, or hours

  • minute, or minutes

  • second, or seconds

  • millisecond, or milliseconds

  • microsecond, or microseconds

  • nanosecond, or nanoseconds

Returns

When base is a Date, a new Date which represents base with offset units added to it.

When base is a Timestamp, a new Timestamp which represents base with offset units added to it.

Examples

The following query returns a Timestamp representing one day after the Unix epoch:

client.query(
  q.TimeAdd(q.Epoch(0, 'second'), 1, 'day')
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
Time("1970-01-02T00:00:00Z")
result = client.query(
  q.time_add(q.epoch(1, "day"), 1, "second")
)
print(result)
FaunaTime('1970-01-02T00:00:01Z')
result, err := client.Query(
	f.TimeAdd(f.Epoch(1, "day"), 1, "second"))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
