# Ensure that we're not at the epoch.  slackpkg breaks with GPG checks when
# the date is so far in the past:

Error: Your system date is wrong.  slackpkg requires that the date be correct
so that the package signatures can be verified.

The date may be incorrect because you have a system such as a Raspberry Pi that
does does not have an RTC (Real Time Clock), or that the correct date was unable
to be read from the RTC due to a driver bug, or a missing driver.

You may wish to set up NTP on your system:
