Date Formulas

Video guide: Learn how to transform dates with formula mode

Date and datetime formulas allow you to work with date and time datapills. These formulas are added to the allowlists for Ruby methods (opens new window), and therefore not all Ruby methods are supported. Reach out to us (opens new window) to add additional formulas to the allowlist.

Date Arithmetic

Use the following keywords to perform arithmetic with date and datetime data:

• seconds
• minutes
• days
• months
• years

When combined with a formula, you can perform addition and subtraction.

Sample usage

Date Arithmetic	Output
"2020-01-01".to_date + 2.days	"2020-01-03"
"2020-01-01".to_date - 2.days	"2019-12-30"
"2020-01-01".to_date + 2.months	"2020-03-01"
"2020-01-01".to_date - 2.months	"2019-11-01"
"2020-01-01".to_date + 2.years	"2022-01-01"
"2020-01-01".to_date - 2.years	"2018-01-01"

now

Returns the time and date at runtime in US Pacific Time Zone (PST).

Sample usage

Formula	Result
now	"2022-02-01T07:00:00.000000-08:00"
now + 8.hours	"2022-02-01T15:00:00.000000-08:00"
now + 2.days	"2022-02-03T07:00:00.000000-08:00"

How it works

The formula calculates the timestamp when the a job is being processed. Each step using this formula will return the timestamp at which the step runs.

Output datapill

If you only want the date without the time, try using the today formula instead.

to_date

This formula converts the input data into a date. Returns the date formatted as YYYY-MM-DD.

Syntax

String.to_date(format: format)

• String - An input datetime or a string that describes a date or datetime.
• format - (optional) The date format of the input written as a string. If not specified, Workato will parse the input string automatically.

Sample usage

Formula	Result
"23-01-2020 10:30 pm".to_date(format: "DD-MM-YYYY")	"2020-01-23"
"01-23-2020 10:30 pm".to_date(format: "MM-DD-YYYY")	"2020-01-23"
"2020/01/23".to_date(format: "YYYY/MM/DD")	"2020-01-23"

How it works

Converts the input data into a date datatype.

Input data best practice

It is recommended to specify the input data format. If the format is not specified, Workato will automatically parse the input string.

The input string must resemble a date for this formula to work.

See also

• strftime: Returns datetime is a custom format.
• to_time: Converts a string to an ISO timestamp.

---

to_time

Converts a string to an ISO timestamp. The response will use the UTC timezone (+00:00).

Syntax

String.to_time(format)

• String - An input string that describes a date or datetime.
• format - The format of the user-defined datetime written as a string.

Sample usage

Formula	Result
"2020-04-02T12:30:30.462659-07:00".to_time	"2020-04-02T19:30:30.462659+00:00"
"2020-04-02".to_time	"2020-04-02T00:00:00.000000+00:00"

How it works

Converts the input string into a datetime datatype. The output datetime will be converted to the UTC timezone (+00:00).

Autofill time

If the input data does not include the time, the output will default to 00:00:00.000000 +00:00.

See also

• strftime: Returns datetime is a custom format.
• to_date: This formula converts the date-like input into a date. Returns the date formatted as YYYY-MM-DD.

Parameters

As shown above, each code (%B, %e, %I, etc.) refers to a specific element of datetime. Static text and punctuation can also be added, such as commas (,), slashes (/), and colons (:). Refer to the following list for frequently used codes:

Sample usage

Formula	Result
today.to_time.to_i	1645660800

How it works

Converts the input datetime into an integer, it will return epoch time in seconds, not milliseconds. The output datetime will be converted to the UTC timezone (+00:00).

Converting between Epoch time to datetime

Convert time formats easily with Workato formulas.

How to Convert Human Readable Time to Epoch Time

Use to_i to convert a datetime datapill to epoch time (in UTC). Learn more about how it works.

How to Convert Epoch Time to Human Readable Time

Use the formula below to convert an epoch time to human readable datetime.

Note that the output will be in UTC timezone (+00:00).

"1970-01-01".to_time +Epoch time.seconds

If you would like to convert epoch time to a specific timezone, you must specify it with in_time_zone.

"1970-01-01".to_time.in_time_zone("US/Pacific") +Epoch time.seconds

Wrong datatype: undefined method `to_i`

Epoch time requires a datetime datapill. If you are using a date datapill, it will cause an error.

Use to_time to convert a date into a datetime before converting to epoch time.
