Which format of a date/time string would be considered cross-platform, cross-database, universal safe?
Would this YYYY-MMM-DD HH:MM:SS be considered safe to use in MySQL, SQLite 2 & 3, MsSQL and other common databases?
How about something like 2010-Jul-12 12:00:00pm?
You could pick a defined standard, such as the ISO standard for date and times. It’s pretty universal and easy to use and understand, and as a defined standard you can just say “all datetimes must be ISO 8601” and be done with it. No worries about locale or cultural confusion.
