[clug] incrementing time

[Duncan Roe]

Hi Boris,

I think the GNU "date" command can do exactly what you want. Look at this:-

 date +%s -d 'Nov 03 07:32:06'
 1067805126

 date +%s -d 'Nov 01 07:32:06'
 1067632326

The man page says:-

 %s     seconds since 1970-01-01 00:00:00 UTC (a nonstandard extension)

Cheers ... Duncan.
