[reportlab-users] Problems Printing Dates & Times

[Rich Shepard]

   I want to print the date and time a report is printed using the python
datetime() module. It's not working as expected.

   At the head of the file I have
 	import datetime

   Some lines down are:

   now = datetime.datetime.now
   pg = canvas.Canvas('impWt.pdf', pagesize=LETTER)
   pg.setFont('Helvetica-Bold', 13)
   pg.drawCentredString(306,760,Title)
   pg.setFont('Helvetica', 10)
   pg.drawCentredString(306,748,now)

   Python apparently can't calculate the string width:

Traceback (most recent call last):
   File "impWtForm.py", line 112, in ?
     compImpWt()
   File "impWtForm.py", line 89, in compImpWt
     pg.drawCentredString(306,748,now)
   File "/usr/lib/python2.4/site-packages/reportlab/pdfgen/canvas.py", line
1179, in drawCentredString
     width = self.stringWidth(text, self._fontname, self._fontsize)
   File "/usr/lib/python2.4/site-packages/reportlab/pdfgen/canvas.py", line
1283, in stringWidth
     return pdfmetrics.stringWidth(text, fontName, fontSize)
   File "/home/rshepard/development/python/reportLab/rl_accel/_rl_accel.c",
line 1102, in stringWidthU
     res = PyEval_CallObjectWithKeywords(_o1, _o2, _o3); if(!res)
ERROR_EXIT();
   File "/home/rshepard/development/python/reportLab/rl_accel/_rl_accel.c",
line 1145, in _instanceStringWidthU
     _o1 = _GetAttrString(text, "decode"); if(!_o1) ERROR_EXIT();
AttributeError: decode

   How should I code this?
