How to Calculate Time Difference in Decimal Format from MySQL Time Fields?

Calculating Time Difference from Time Fields in MySQL

You have a MySQL database with a 'time' field that stores event occurrence times in minutes:seconds format. To determine the total time elapsed between two events, it becomes necessary to convert these values into a decimal format.

To accomplish this, you can utilize the TIMESTAMPDIFF function provided by MySQL:

<code class="sql">TIMESTAMPDIFF(MINUTE, T0.created, T0.modified)</code>

• The TIMESTAMPDIFF function calculates the difference between two timestamps or time values.
• MINUTE signifies that you want the result in minutes.
• T0.created and T0.modified represent the timestamps of the first and second events, respectively.

This function will provide you with the total elapsed time in minutes. To express it as a decimal, you can simply divide the result by 60. For instance, in the example provided, the result would be:

<code class="sql">60 minutes / 6.67 minutes = 8.97</code>

This gives you the precise decimal representation of the time difference between the two events. Refer to the MySQL documentation for additional information on the TIMESTAMPDIFF function: https://dev.mysql.com/doc/refman/5.7/en/date-and-time-functions.html#function_timestampdiff.
