Hi, should I say "1400 hours is a better time" or "1400 hours is a better timing" ?
Thanks

If you mean 1400 hours = 2 PM, as in "1400 would be a better time to meet" then you want "time".
I can't think of any context in which you would use "timing" with the indefinite article. Perhaps abbied can.
"Timing" can also mean (Merriam Webster)
a : placement or occurrence in time {the timing of the sale couldn't have been better}
b : the ability to select the precise moment for doing something for optimum effect {a boxer with impeccable timing}
Regarding the sense of "to measure how long it takes for something to happen or for someone to do something"--

Non-Americans will need to be told, and some Americans will need to be reminded, that "These are the times that try men's souls" was the first line of The Crisis #1, the first of a series of pamphlets by the revolutionary agitator-propagandist Thomas Paine. The first one came out during the darkest days of the American Revolutionary War.
