Something I'm wondering about is the correct usage of the word(s) 'timestamp'. I don't know whether it's one (timestamp) or two (time stamp) words, and googling for the answer doesn't help me in finding an answer.
Consulting two sources which I believe to be reliable ones:
Oxford Dictionaries (which looks like it's affiliated with the actual university) says it's 'timestamp';
whereas Merriam-Webster says it's 'time stamp'.
Oxford Dictionaries is British and Merriam-Webster is American, and I'm assuming these sites reflect their respective spelling rules. Which may explain the difference here. However, if I'm not mistaken, with words like these it's normally the other way around; i.e. the American spelling using it as one concatenated word, and the British spelling as two separate words.
Is my assumption about the American vs. Brisish spelling correct? Which, if any, of the two forms is correct?
