| How CURRENT_TIMESTAMP is stored is of no interest. You are not working with database files directly. |

Hey
I was discussing with sm@rty the 'modified' field definition we had used in our MYSQL cache resource in the demo folder where we used MSQL's 'CURRENT_TIMESTAMP' which is a string.

CURRENT_TIMESTAMP is string date time. |
CURRENT_TIMESTAMP is a timestamp, not a string.
You can use it in any datetime context directly.
|
You brought up that it is not a string which, was a wrong statement.... |

Judging from your code, you was doing it wrong all along, to begin with.
Retrieving a ready to use UNIX timestamp only to convert it back and forth, instead of comparing two timestamps directly, is. Just. Plain. Wrong. |

Again wrong! Not converting it back and forth. MYSQL does update 'CURRENT_TIMESTAMP' internally on each record update so it's not depending on some timestamp you provide. |

| "Provide" what? You can compare it with timestamp from your template file. |

If you update the template in the database you do not need to assign a timestamp value to the 'modified' field. MYSQL does fill it automatically (as string). |
