tshddx / shift-date-to-utc.js
Last active September 12, 2022 19:28
JavaScript utility to shift a date to UTC
/*
Note: if you only want to format a date as a string and not do any date
manipulation, you can use provided formatting functions to specify a time zone:
const date = new Date(dateString);
const formattedDate = date.toLocaleDateString('en-US', { timeZone: 'UTC' });
All JavaScript Date objects are in the browser's local time zone. There's no way
around that. This means that if you receive a date string from the backend and
create a Date object with `new Date(unixTimestampOrISOString)` that Date object

We can make this file beautiful and searchable if this error is corrected: It looks like row 7 should actually have 12 columns, instead of 1 in line 6.
