for hevea 1.08-4: Extra Features -> Date and time file:///usr/share/doc/hevea/html/manual032.html#toc98

Date and time support is not enabled by default, for portability and simplicity reasons.

However, HEVEA source distribution includes a simple (sh) shell script xxdate.exe that activates date and time support. The hevea command, should be invoked as :

# hevea -exec xxdate.exe ...

This will execute the script xxdate.exe, whose output is then read by HEVEA. As a consequence, standard LATEX counters year, month, day and \ime are defined and LATEX command \today works properly. Additionnally the following counters and commands are defined :

Counter weekday, Hour, hour, minute…

To change the date format from European to US, make the following modification:
