Ooh, let's not do this this way (unless you like having this exact same PR twice a year). Instead, either:

• If this code runs on a robot, move adjusting the timestamp to someplace that is not on a robot; this possibly includes "google sheets", making it known in the data that the time is in UTC and doing something gross like this: https://davidkeen.com/blog/2017/01/time-zone-conversion-in-google-sheets/ because google doesn't do timezone conversion for some reason (?)
• If this code runs on a laptop, which would indeed be happy and is what it looks like, then instead of doing timestamp = datetime.datetime.now() you can do timestamp = datetime.datetime.now(tz=tzinfo.utcoffset(0)) (tzinfo.utcoffset will generate the appropriate time zone info for the conversion), which also will work even if you run this script with a locale and timezone set to somewhere other than new york for whatever reason.

Nice!
