I have an accounts page which lets you put in a DateTime as follows:
<input type="date" class="form-control" placeholder="Date" name="date" autocomplete="off" required>
<input type="time" class="form-control" placeholder="Time" name="time" autocomplete="off" required>
When the form is submitted, I want to convert them from PST
(which is what they were entered in) to UTC
(what my backend is in). How can I do this? Thanks!
