From Discord: Converting Zoned DateTime to UTC in Effect Typescript

[effect-bot]

Summary

In the chat, jessekelly is trying to convert a DateTime.Zoned object to DateTime.Utc within the Effect Typescript library. They express some difficulty in finding a straightforward method for this conversion. whatthebluck suggests using DateTime.setZone, but it is not applicable for converting from a zoned time to UTC. jessekelly points out that simply calling .make on a Zoned object returns an Option<DateTime.Zoned>, not what they need.

jessedkelly explains that they need the Zoned type on the frontend for parsing user-related time expressions like "today" or "tomorrow" in the user's timezone. rjdellecese suggests extracting epochMillis from the DateTime.Zoned and manually constructing a DateTime.Utc object as a workaround.

Key Takeaways:

• There seems to be a gap in the Effect Typescript library for easily converting a Zoned DateTime to a Utc DateTime.
• Users discussed workarounds, like using epochMillis, but acknowledge the need for a more straightforward API for this conversion.
• This topic is relevant to both participants as they are dealing with user-specific timezone data.
