Does the YYYY-MM-DD HH:MM:SS datetime format have a special name? I am writing a function that returns a date in this format and I'm trying to figure out what to call the function.
回答1:
I can't find a source, but in my experience (25 years working as a systems programmer in UNIX environments) this format is referred to colloquially among engineers as Yoda Time.
It's not valid ISO 8601 because it uses a space instead of a T to separate the date and time parts.
回答2:
It looks a lot like ISO 8601 format, but you can never be too sure with time formats.
回答3:
I think its a variation on the ISO 8601 format. There is more info regarding the format here:
