I personally would take it as 1 second past Friday night. But I would ask the person to clarify. Date changes occur at midnight. One second later is AM on Friday. Altogether, the words themselves taken at face value would seem to mean no later than AM Friday morning.
In my experience, and in agreement with other flutherites here, the usage of this particular vernacular implies that you have until the end of the calendar day Friday, PM to complete the task. Like taxes have to be posted by midnight on April 15th means any time before the date changes to April 16th.
It depends on the person stating it. One of my professors stated the similar and she did not mean Friday night. She meant 12am on Friday morning just after Thursday. Another professor of mine meant the other referring to just before midnight Saturday or PM Friday. It is always best to check with the person to make sure you are understanding them correctly though because depending upon their background and personal views they may have a different preconception than you.
This question is in the General Section. The abbreviations for am and pm come from the Latin words "ante meridies" am and "post meridies" pm. Meridies means noon, so post meridies means after noon and ante meridies means before noon.
In hour time notation, "" and "" refer to midnight at the start of a given date. TL;DR: "Midnight" should only be used where the night is certain or conceptional. Conceptionally the individual night does not matter. In denoting a specific point in time, clarify the night not just the day - especially when on a deadline. Colloquial use can be a strong argument if a term stands firm in the language. If you are reading this then the term does not stand firm.
Ultimately, you will have to observe or ask others how they use "midnight [of xday]" - which is how colloquiality arises. Colloquere, colloquere! In the same way, "midnight" relates to a certain or conceptional night, not a day. While definition-wise midnight should be neither AM nor PM, from philosophical and technical points midnight is both preceeding and succeeding some midday thus being both AM and PM; dito midday. Binding midnight and midday to AM or PM and still avoiding ambiguity requires understood convention which works in small, agreeing and identified groups only and so makes for bad use in wider language where the group and convention of a speaker is not easily identified.
It may be more useful to have 12 CM contra meridiem, opposite midday for midnight and 12 HM hoc meridiem, this midday for midday - relating to conceptional terms rather than any specific midday or day. So while "12am" may claim to be before midday it may just be treated as a synonym to "12pm" marrying the arguments of Damovisa and Hellion - with both designations being utterly useless to disambiguate except for standing convention.
So the "12" may be more significant. I do not know of any clock as opposed to what is called a "timer" - ugh , calendar or other time-giver counting time down. Assuming a count-up, "12" has come after some "11" and something has been counting up a dozen times. That rather relates "12am" to whatever happened before.
This could argue for midnight belonging to the day before. There could be an argument for convenience here if "nearest" was effectually defined. Time-wise, or is no further away and offers no less convenience. This replaced the ambiguity of "X's midnight" with that of "night of the date".
This can only help if the night is sufficiently specified by the date which may not be the case. Y Our mission, syctai, is to clarify the night before using "midnight" - unless speaking conceptionally. Sign up to join this community. The best answers are voted up and rise to the top.

There are no standards established for the meaning of 12am and 12pm. It is often said that 12am Monday is midnight on Monday morning and 12pm is midday. This puts all the times beginning with 12 and ending with am in the same one-hour block, similarly with those ending with pm.
It can also be argued that by the time you have seen a clock showing at midday it is already post meridiem, and similarly at midnight it is already ante meridiem. Times in the first hour of the day are sometimes given as, for example, am, with am corresponding to midnight, but with a time twelve hours later given as pm.
Another convention sometimes used is that, since 12 noon is by definition neither ante meridiem before noon nor post meridiem after noon , then 12am refers to midnight at the start of the specified day and 12pm to midnight at the end of that day Given this ambiguity, the terms 12 am or 12 pm should be avoided in order to provide a simple definition of midnight.
