Read the article time_ampmto24 - Lasso 8 custom tag converts a time with an AM/PM designation to 24-hour time.
[time_ampmto24] converts a time with an AM/PM designation to 24-hour time. This tag accepts a time formatted as hh:mm AM|PM, and converts the time to hh:mm:ss 24-hour time format. This makes it easy to write the value to a database.
Programmers needlessly make it awkward to enter times into forms, especially when the time is broken into three select menus (hours, minutes, am/pm). Some programmers are lazy and trust users to enter a time in a "correct" format, but that leads to user errors. To mitigate the user interface issue, I use the jQuery plugin, Time Entry.
