The DTML User Guide has an "Appendix A" that shows lot's of options, but no examples. Anyhow, see: http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.18.html You can use these like so: <dtml-var ZopeTime fmt=="%Y/%m/%d"> <dtml-var ZopeTime fmt=="AMPM"> <dtml-call "REQUEST.set('d_Date',ZopeTime().strftime('%Y/%m/%d'))"> <dtml-var d_Date> <dtml-call "REQUEST.set('d_Date',ZopeTime().strftime('AMPM'))"> <dtml-var d_Date> You can also use Python slicing syntax to do something totally ridiculous like this: <dtml-call "REQUEST.set('z_t',ZopeTime())"> <dtml-call "REQUEST.set('z_sec',_.int(z_t))"> <dtml-call "REQUEST.set('day_t',_.string.split(_.str(z_t))[1])"> <dtml-call "REQUEST.set('hour_sec',_.int(_.string.split(day_t,':')[0]) * 3600)"> <dtml-call "REQUEST.set('min_sec',_.int(_.string.split(day_t,':')[1]) *60)"> <dtml-call "REQUEST.set('sec_t',_.string.split(day_t,':')[2])"> <dtml-call "REQUEST.set('sec_sec',_.int(_.string.split(sec_t,'.')[0]))"> <dtml-call "REQUEST.set('sum_sec', hour_sec + min_sec + sec_sec - 1)"> <dtml-call "REQUEST.set('start_sec', _.int(z_t) - sum_sec)"> <dtml-call "REQUEST.set('end_sec', start_sec + 86398)"> <dtml-var "_.DateTime(start_sec)" fmt="AMPM"><br> <dtml-var "_.DateTime(end_sec)" fmt="AMPM"><br> to find the first and last seconds of a date.
