check for new file over 24 hrs

Hi all,
I am trying to figure out a method to flag an error if a file has not arrived in a certain directory within 24 hrs of the last one arriving.
I am currently writing the time to a file when a file is recieved. I then want to check for a new file reguarly but flag an error if it has been over 24 hrs since a file was received. However i cannot work out how to test for a 24 hour period as the script will be run at irregular intervals.
Any ideas?

Thanks

NAME
ps2pdf - Convert PostScript to PDF using ghostscript ps2pdf12 - Convert PostScript to PDF 1.2 (Acrobat 3-and-later compatible) using ghostscript ps2pdf13 - Convert PostScript to PDF 1.3 (Acrobat 4-and-later compatible) using ghostscript ps2pdf14 - Convert PostScript to PDF 1.4 (Acrobat 5-and-later compatible) using ghostscript SYNOPSIS
ps2pdf [options...] {input.[e]ps|-} [output.pdf|-] ps2pdf12 [options...] {input.[e]ps|-} [output.pdf|-] ps2pdf13 [options...] {input.[e]ps|-} [output.pdf|-] ps2pdf14 [options...] {input.[e]ps|-} [output.pdf|-] DESCRIPTION
The ps2pdf scripts are work-alikes for nearly all the functionality (but not the user interface) of Adobe's Acrobat(TM) Distiller(TM) prod- uct: they convert PostScript files to Portable Document Format (PDF) files. If the output filename is not specified, the output is placed in a file of the same name with a '.pdf' extension in the current working directory. Either the input filename or the output filename can be '-' to request reading from stdin or writing to stdout, respectively, when used as a filter. The three scripts differ as follows: - ps2pdf12 will always produce PDF 1.2 output (Acrobat 3-and-later compatible). - ps2pdf13 will always produce PDF 1.3 output (Acrobat 4-and-later compatible). - ps2pdf14 will always produce PDF 1.4 output (Acrobat 5-and-later compatible). - ps2pdf per se currently produces PDF 1.4 output. However, this may change in the future. If you care about the compatibility level of the output, use ps2pdf12, ps2pdf13 or ps2pdf14, or use the -dCompatibility=1.x switch in the command line. There are some limitations in ps2pdf's conversion. See the HTML documentation for more information. A large number of Adobe Distiller(TM) parameters which can be used to control the conversion are also documented there, including instructions for generating PDF/X and PDF/A documents. OPTIONS
The ps2pdf scripts use the same options as gs(1). EXAMPLES
Converting a figure.ps to figure.pdf: ps2pdf figure.ps A conversion with more specifics: ps2pdf -dPDFSETTINGS=/prepress figure.ps proof.pdf Converting as part of a pipe: make_report.pl -t ps | ps2pdf -dCompatibility=1.3 - - | lpr SEE ALSO
gs(1), ps2pdfwr(1), Ps2pdf.htm in the Ghostscript documentation BUGS
