I’m working with a custom PHP PDO database wrapper that automatically handles date_created and date_modified columns. The script uses PHP’s time() function which returns Unix timestamps like 1455771305.
I tried using MySQL’s TIMESTAMP column type but I’m getting warnings when inserting data:
INSERT INTO users
(username, password_hash, date_created)
VALUES
('testuser', 'abc123', '1455771891');
This gives me: Warning: #1265 Data truncated for column 'date_created' at row 1
I know frameworks like Laravel handle this automatically, but I need to create the columns manually. What MySQL column type works best for storing Unix timestamp integers from PHP’s time() function? Should I be using INT instead of TIMESTAMP, or is there a better approach?
TIMESTAMP wants MySQL datetime format like ‘2016-02-18 10:28:11’, not raw Unix integers. That’s your truncation warning right there. I ditched TIMESTAMP for BIGINT UNSIGNED after hitting timezone bugs in a multi-region app. BIGINT handles Unix timestamps directly - no format conversion needed, plus you skip the 2038 limit that bites INT. Your PDO wrapper can dump time() values straight in. Need human-readable dates for admin stuff? Just wrap it with FROM_UNIXTIME() in your SELECT. Way better than wrestling with MySQL’s automatic timezone conversions - handle that logic in PHP instead.
Everyone’s arguing TIMESTAMP vs INT, but you’re missing the real issue. Why manually handle these columns when you can automate everything?
I built something like this for our user system but went way further. Created automation that intercepts your time() calls and handles all the database stuff automatically. No more manual column definitions or format conversions.
It detects timestamp operations and picks the right MySQL type based on what you need. Want readable dates for debugging? It converts to DATETIME. Want performance? Uses BIGINT UNSIGNED for raw Unix values.
Best part - your PHP code doesn’t change at all. The automation sits between your PDO wrapper and MySQL, handling type matching and conversions behind the scenes.
We’ve used this across 15 apps. Zero timestamp warnings, zero 2038 issues, and the database shows whatever format makes sense for each case.
Why write wrapper code when you can just automate it?
Yeah, INT works but it’s a maintenance nightmare. Try debugging raw timestamps in the database at 2am - you’ll hate life.
I automate the conversion now. Set up a workflow that grabs your PHP time() output and converts it to DATETIME before it hits MySQL. You get readable dates AND skip TIMESTAMP’s weird limitations.
Built this for our user registration system. The automation handles Unix conversion behind the scenes, so PHP stays clean but the database shows actual dates. No more deciphering cryptic numbers when things break.
Keep your PHP wrapper simple, let the database store human-readable dates. Automation handles the gap and saves you timezone hell down the road.
for sure! mysql TIMESTAMP needs datetime, not unix. those warnings are from that mismatch. just go with INT(11) for your time() outputs. super easy and no need for extra conversions between php and mysql. been doing it this way for ages!
had this issue too. mysql TIMESTAMP is for datetime strings, not unix timestamps. switch it to INT(10) UNSIGNED, and u won’t get any more warnings. php time() values will go in just fine, no extra work needed!
You’re getting this error because MySQL’s TIMESTAMP expects datetime format, not Unix timestamps. When you pass an integer like 1455771891, MySQL tries to read it as datetime and throws the truncation warning. Use INT(10) UNSIGNED instead for storing PHP time() output. It gives you the full range for Unix timestamps and matches what time() returns perfectly. I’ve used this for years without problems. The main benefit? Simplicity. No conversion between PHP and MySQL - just store the integer and convert back to readable format in PHP with date() when you need it. TIMESTAMP has the 2038 problem and timezone headaches that you dodge with plain integers. If you really want MySQL’s native date functions, you’d convert with FROM_UNIXTIME() during insertion, but that just adds complexity to your wrapper.
You’re getting that warning because MySQL’s TIMESTAMP expects datetime strings, not Unix timestamps. I hit this exact issue when migrating from a legacy system that stored everything as Unix timestamps. Just use INT UNSIGNED or BIGINT UNSIGNED to store the raw Unix timestamp values from PHP’s time(). You’ll get better compatibility and performance since MySQL won’t need to convert between formats. Your PHP wrapper keeps working without any changes, and you can convert to readable dates in SELECT queries using FROM_UNIXTIME() when you need them for reports or debugging.
