This is a time point method for the `seq()`

generic. It works for sys-time
and naive-time vectors.

Sequences can be generated for all valid time point precisions (daily through nanosecond).

When calling `seq()`

, exactly two of the following must be specified:

`to`

`by`

Either

`length.out`

or`along.with`

## Usage

```
# S3 method for clock_time_point
seq(from, to = NULL, by = NULL, length.out = NULL, along.with = NULL, ...)
```

## Arguments

- from
`[clock_sys_time(1) / clock_naive_time(1)]`

A time point to start the sequence from.

`from`

is always included in the result.- to
`[clock_sys_time(1) / clock_naive_time(1) / NULL]`

A time point to stop the sequence at.

`to`

is cast to the type of`from`

.`to`

is only included in the result if the resulting sequence divides the distance between`from`

and`to`

exactly.- by
`[integer(1) / clock_duration(1) / NULL]`

The unit to increment the sequence by.

If

`by`

is an integer, it is transformed into a duration with the precision of`from`

.If

`by`

is a duration, it is cast to the type of`from`

.- length.out
`[positive integer(1) / NULL]`

The length of the resulting sequence.

If specified,

`along.with`

must be`NULL`

.- along.with
`[vector / NULL]`

A vector who's length determines the length of the resulting sequence.

Equivalent to

`length.out = vec_size(along.with)`

.If specified,

`length.out`

must be`NULL`

.- ...
These dots are for future extensions and must be empty.

## Examples

```
# Daily sequence
seq(
as_naive_time(year_month_day(2019, 1, 1)),
as_naive_time(year_month_day(2019, 2, 4)),
by = 5
)

#> [6] "2019-01-26" "2019-01-31"
# Minutely sequence using minute precision naive-time
