# mozcodate2iso8601 converts date strings in the format used for MOZ_CO_DATE
|
||
|
|
# into ISO 8601. MOZ_CO_DATE is the date specification used with
|
||
|
|
# "cvs checkout -D". It is set by tools/tinderbox/build-seamonkey-util.pl
|
||
|
|
# for automated builds when UseTimeStamp is turned on. Note that UseTimeStamp
|
||
|
|
# is usually off for release builds, which come from a fixed CVS tag. Most
|
||
|
|
# non-automated buids also don't have MOZ_CO_DATE set. To handle those
|
||
|
|
# cases, this script will also accept no argument or an empty argument and
|
||
|
|
# exit without failing or producing any output.
