DateTime localtime inconsistency

#1

The hour of the local time is different when converted to a unix timestamp and then back to local time.
Expected behavior is that that the dates match.

print(DateTime.fromUnixTimestamp(DateTime.fromLocalTime(2025, 3, 10).UnixTimestamp):ToLocalTime())
returns

    ["Day"] = 10,
    ["Hour"] = 1,
    ["Millisecond"] = 0,
    ["Minute"] = 0,
    ["Month"] = 3,
    ["Second"] = 0,
    ["Year"] = 2025

I believe that this is related to daylight saving time. This is because the bug does not reproduce if the day is set to the 9th. I am in the US West timezone if that is necessary to reproduce.

I believe that I’m experiencing the same problem. I’m writing code to get the current hour of the day in local time:

local currentHour = tick() % (60 * 60 * 24) / (60 * 60)

At the time of writing this, I get the following output (12:19 Eastern Daylight Time, as indicated by the timestamp):

We should get 12.32 to reflect that this is the 12th hour in EDT, not the 11th.

Running this same code except using os.time():

Which is the expected result for 4:20 PM UTC.
