Most timestamps in WorkRamp are listed in UNIX time in milliseconds. For example, a date on February 26th, 2017 would be equivalent to "1488145254000"
Most libraries should be able to convert/handle these timestamps in your application.
For manual reference, you can convert timestamps online here: http://www.epochconverter.com/
Other Date FormatsSome endpoints use the ISO8601 date format. Please check each endpoint that you use for the specific formats of input and response. We are in the process of updating the API to make ISO8601 timestamps accepted by all inputs and available as an option in all responses (while preserving the original fields to maintain backward compatibility).
