We will be sending out daily Event Alert emails (via Mandrill) containing the date and time of upcoming events.

We are having difficulty getting the date and time text to be consistently recognised by email clients as a valid Date & Time, so that the text in email, on both mobile and desktop, is easily selectable to Add to Calendar (example of what we're looking to achieve attached). Mostly it appears to be unrecognised text. Note: we have tested reordering the formats for the time/date text, but cannot achieve consistency.
