Question 1

How do I parse a string date with Timex?

Accepted Answer

Use Timex.parse/2 or Timex.parse!/2 with format strings, such as {ISO:Extended} for ISO dates or strftime patterns. The README provides examples like parsing ISO and strftime formats in the Quickfast introduction.

Question 2

Timex or Elixir's built-in DateTime: which is better?

Accepted Answer

Timex is better for complex operations like timezone handling, intervals, and advanced formatting. For simple date arithmetic without timezones, the standard library may suffice and reduce dependencies, as suggested in the migration notes.

Question 3

How to handle timezone conversions in Timex?

Accepted Answer

Use Timezone.get/2 to retrieve timezone info and Timezone.convert/2 to convert datetimes. The README shows examples with 'America/Chicago' timezone conversions in the Quickfast introduction.

Question 4

Can I use Timex with custom date types?

Accepted Answer

Yes, by implementing the Timex.Protocol for your custom types. This allows them to work with all Timex functions, as described in the Extensibility section of the README.

Question 5

What are common issues when upgrading Timex?

Accepted Answer

APIs may have changed or been renamed, so review the CHANGELOG and documentation. Backward compatibility is limited, requiring code adjustments for migration from version 2.x or earlier, as warned in the migration section.

Question 6

How to format relative time like '3 minutes ago' with Timex?

Accepted Answer

Use Timex.shift/2 to adjust the datetime and Timex.format/2 with the {relative} format option. The Quickfast introduction demonstrates this with an example of shifting minutes and formatting.
